A cryogenic test facility specifically designed for cooling sequentially the eight coils making the Barrel Toroid (BT) has been fully commissioned and is now ready for final acceptance of these magnets. This facility, originally designed for testing individually the 46 tons BT coils, will be upgraded to allow the acceptance tests of the two End-Caps, each of them having a 160 tons cold mass. The integrated system mainly comprises a 1.2 kW@4.5 K refrigerator, a 10 kW liquid-nitrogen precooler, two cryostats housing liquid helium centrifugal pumps of respectively 80 g/s and 600 g/s nominal flow and specific instrumentation to measure the thermal performances of the magnets. This paper describes the overall facility with particular emphasis to the cryogenic features adopted to match the specific requirements of the magnets in the various operating scenarios.

More than 1700 cryomagnets working at 1.9 or 4.5 k will form part of the magnetic lattice of the LHC. The beam pipe passage from cryogenic temperatures to room temperature zones will be achieved by 200 cold to warm transitions (CWTs). The CWTs will compensate for longitudinal and transversal displacements between beam screens and cold bores, ensuring vacuum continuity without limiting the aperture for the beam. The transverse impedance contribution is kept below the assigned total budget of 1 MO/m by means of a 4 µm thick Cu coating that also minimises the dynamic heat load through image currents. Tests have been performed that confirm that the static heat load per CWT to the cryomagnets remains below 2.5 W, hence validating the design.

Recent contracts have been placed by the Organization for the delivery of quantities up to 280 tons of liquid helium over four years and up to 50000 tons of liquid nitrogen over three years. Main users are the very large cryogenic system of the LHC accelerator complex, the physics experiments using superconducting magnets and liquefied gases and all the related test facilities whether industrial or laboratory scale. With the commissioning of LHC, the need of cryogens at CERN will considerably increase and the procurement policy must be adapted accordingly. In this paper, we discuss procurement strategy for liquid helium and nitrogen, including delivery rates, distribution methods and adopted safety standards. Global turnover, on site re-liquefaction capacity, operational consumption, accidental losses, purification means and storage capacity will be described. Finally, the short to medium term evolution of the Organization’s requirements will be reviewed.

The precise positioning of the heavy magnets and the stringent thermal budgets imposed by the machine cryogenic system, require a sound thermo-mechanical design of the support system. Each support is composed of a main tubular thin-walled structure in glass-fibre reinforced epoxy resin, with its top part interfaced to the magnet at 1.9 K and its bottom part mounted onto the cryostat vacuum vessel at 293 K. In order to reduce the conduction heat in-leak at 1.9 K, each support mounts two heat intercepts at intermediate locations on the column, both actively cooled by cryogenic lines carrying helium gas at 4.5-10 K and 50-65 K. The need to assess the thermal performance of the supports has lead to setting up a dedicated test set-up for precision heat load measurements on prototype supports. This paper presents the thermal design of the support system of the LHC arc magnets. The results of the thermal tests of a prototype support made in industry are illustrated and discussed. A mathematical model has been set up and refined by the comparison with test results, with the scope of extrapolating the observed thermal performance to different geometrical and material parameters. Finally, the calculated estimate of the heat load budgets of the support system and their contribution to the total cryogenic budget for an LHC arc are presented.

Two or three column-type support posts sustain each cryomagnet. The choice of a convenient material for these supports is critical, because of the required high positioning accuracy of the magnets in their cryostats and stringent thermal budget requirements imposed by the LHC cryogenic system. A glass-fibre/epoxy resin composite has been chosen for its good combination of high stiffness and low thermal conductivity over the 2-293 K temperature range. Plies of long glass-fibres are stacked optimally yielding the best mechanical behaviour. However, heat leaks from the supports are influenced by the thermal characteristics of the composite, which in turn depend on the orientation of the fibres. To study the dependence of the thermal conductivity on fibre's orientation, we performed high precision thermal conductivity measurements of various samples of glass-fibre/epoxy resin composite. The results of the thermal conductivity measurements are compared with integral measurements on support posts for LHC cryomagnets and with mixing models.

Direct cooling of the krypton by nitrogen is used in emergency cases, while an intermediate cooler, containing saturated liquid argon at around 10 bar (117 K) is used under normal operation conditions when high thermal stability is needed. The krypton pressure is, during data taking, regulated to a value of (1.05 $\pm$ 0.01) bar for a period of about 8 months of continuous operation of the calorimeter.

They are installed in the experimental areas of the electron-positron collider LEP and the proton (and heavy ion) accelerator SPS for the observation of high-energy interactions of elementary particles. The typical cold mass of a detector magnet ranges from 1 to 40 tons, and typical cryoplant cooling capacities are between 400 and 800 W/4.5 K entropy equivalent. Operation must be very flexible to meet the varying experimental requirements. We intend to present technical data of the system and statistics from over 180'000 running hours during the four years from 1992 to 1995. Operation includes phases of cool-down, steady-state cooling, recovery after magnet quench or other incidents and warm-up of the superconducting magnets. Emphasis will be laid on the analysis of fault conditions, multiple interaction between perturbations and consequences for the users of liquid helium supply interruption.

The refrigeration plant will at first be installed in a surface building for the tests of the superconducting magnet. On completion of the tests the cold box will be moved to its final underground position next to the CMS experimental cavern.

Two separated helium refrigerators will be used to allow cool-down from ambient temperature and steady-state operation at 4.5 K of all the magnets having a total cold mass of about 600 tons. In comparison with the preliminary design, the helium distribution scheme and interface with the magnet sub-systems are simplified, resulting in a considerable improvement of the operational easiness and the overall reliability of the system at some expense of the operational flexibility. The paper presents the cryogenic layout and the basic principles for magnets cool-down, steady state operation and thermal recovery after a fast energy dump. 991214SLAC CERN EDS SIS INSP2000 6587929 SIS:2000 PR/LKR added SIS ARC-PR-2007 CLAS1 LHC-PROJECT-REPORT SzGeCERN Accelerators and Storage Rings ARTICLE CERN LHCPROJECTREPORT CERN LHC ATLAS INSPEC A0720M (Cryogenics) INSPEC A2940P (Semiconductor detectors) INSPEC A2940B (Ionisation chambers) INSPEC A2940T (Position sensitive detectors) INSPEC A2940M (Scintillation detectors; scintillators and photomultipliers) INSPEC A0755 (Magnetic instruments and techniques) INSPEC B3240E (Superconducting coils and magnets) INSPEC B7420 (Particle and radiation detection and measurement) INSPEC NI mass: 6 INSPEC cooling INSPEC cryogenics INSPEC liquid-ionisation-chambers INSPEC low-temperature-production INSPEC position-sensitive-particle-detectors INSPEC semiconductor-counters INSPEC solid-scintillation-detectors INSPEC superconducting-coils INSPEC superconducting-magnets Haug, F Passardi, Giorgio ten Kate, H H J LHC 1511-13 1 IEEE Trans.

A centrifugal pump will be used, providing a mass flow of 1.2 kg/s and a differential pressure of 40 kPa (ca. 400 mbar) at about 4300 rpm. Two pumps are foreseen, one for redundancy, in order to feed in parallel the cooling circuits of the Barrel and the two End-Caps toroid magnets. The paper describes the tests carried out at CERN to measure the characteristic curves, i.e. the head versus the mass flow at different rotational speeds, as well as the pump total efficiency. The pump is of the "fullemission" type, i.e. with curved blades and it is equipped with an exchangeable inducer. A dedicated pump test facility has been constructed at CERN, which includes a Coriolis-type liquid helium mass flow meter. This facility is connected to the helium refrigerator used for the tests at CERN of the racetrack magnets of the Barrel and of the End-Cap toroids.

The superconducting magnet used to provide the required magnetic field consists of four sub-systems: a central solenoid and a very large toroidal magnet comprising two end-cap magnets and the barrel toroid magnet. The associated cryogenic system, currently in the final specification and procurement phase has been sub-divided into three parts: internal, proximity and external. The internal cryogenics minimizes and extracts the heat loads to/from the 4.5 K cold mass and its thermal shields, while the proximity cryogenics takes the cooling capacity generated by the external common system and distributes it to the four magnets according to the various operating scenarios. Two independent proximity cryogenic systems have been designed taking into account the difference in cooling principle of the solenoid and the three toroids, respectively. 20011207SLAC CERN EDS SIS COSCI2002 SIS AIP_ART2005 SIS:2005 PR/LKR added SIS ARC-PR-2007 CLAS1 LHC-PROJECT-REPORT SzGeCERN Accelerators and Storage Rings ARTICLE CERN LHCPROJECTREPORT CERN LHC ATLAS Bradshaw, T Brown, G AUTHOR|(CDS)2077180 #BEARD# Cragg, D Crook, M Haug, F Mayri, C Orlowska, A H Passardi, Giorgio Pengo, R ten Kate, H H J Rochford, J Sole, D LHC 155-160 AIP Conf.

The large coil will be made of a four layers winding generating the 4 T uniform magnetic induction required by the detector. The length of the solenoid is 13 m with an inner diameter of 5.9 m. The mass kept at liquid helium temperature totals 220 t and the electromagnetic stored energy is 2.7 GJ. The windings are indirectly cooled with a liquid helium flow driven by a thermosyphon effect. The external cryogenic system consists of a 1.5 kW at 4.5 K (entropy equivalent) cryoplant including an additional liquid nitrogen precooling unit and a 5000 litre liquid helium buffer. The whole magnet and cryogenic system will be tested at the surface by 2003 before final installation in the underground area of LHC.

The magnets will be tested individually in a 5000 m2 experimental area prior to their final installation at an underground cavern of the LHC Collider. For the BT magnets, a dedicated cryogenic test facility has been designed which is currently under the construction and commissioning phase. A liquid nitrogen pre-cooling unit and a 1200 W@4.5K refrigerator will allow flexible operating conditions via a rather complex distribution and transfer line system. Flow of two-phase helium for cooling the coils is provided by centrifugal pumps immersed in a saturated liquid helium bath. The integration of the pumps in an existing cryostat required the adoption of novel mechanical solutions. Tests conducted permitted the validation of the technical design of the cryostat and its instrumentation. The characteristics of one pump were measured and pressure rise of 300 mbar at nominal flow of 80 g/s confirmed the specifications.

The total liquid argon fill of the three cryostats is 83 m3. Gas bubble formation which is detrimental for the functioning of the detector is avoided by sub-cooling of the liquid argon volume with saturated liquid nitrogen heat exchangers placed in the cryostats. Furthermore, to prevent degradation of the detector performance, the maximum temperature gradient across the total liquid volume must be kept within 0.6 K. Additional severe constraints are imposed by the request of uninterrupted cryogenic operation during several years and by the safe handling of a large amount of argon in a 100 m deep underground area.

For the detection of the elastically scattered particles at very small angles with respect to the beams edgeless silicon detectors will be contained in 36 small vacuum vessels called “roman pots” to be installed inside the LHC beam vacuum pipe. The final -not yet fixed-operating temperature is expected to be between 130 K and 220 K. The preferred cooling method applies a combination of cryogenic heat pipes and pulse tube refrigerators.

The mechanical tolerances of the modules being constructed are stringent, making the large scale fabrication of detector modules a challenge. An assembly procedure has been developed with the aim of meeting the required mechanical tolerances. The production of four prototype mechanical modules using this procedure is described. Improvements of the assembly technique planned for the production of future forward modules are outlined.

Two test campaigns have taken place on B0, at the CERN facility where the individual BT coils are about to be tested. The first campaign aimed to test the cool-down, warm-up phases and to commission the coil up to its nominal current of 20.5 kA, reproducing Lorentz forces similar to the ones on the BT coil. The second campaign aimed to evaluate the margins above the nominal conditions. The B0 was tested up to 24 kA and specific tests were performed to assess: the coil temperature margin with respect to the design value, the performance of the double pancake internal joints, static and dynamic heat loads, behavior of the coil under quench conditions. The paper reviews the overall test program with emphasis on second campaign results not covered before. 10 Refs.

The magnet configuration is based on an inner superconducting solenoid and large superconducting air-core toroids (barrel and two end-caps) each made of eight coils symmetrically arranged outside the calorimetry. The total cold mass approaches 600 tons and the stored energy is 1.7 GJ. The cryogenic infrastructure will include a 6 kW @ 4.5 K refrigerator, a precooling unit and distribution systems and permits flexible operation during cool-down, normal running and quench recovery. A dedicated LN2 refrigeration system is proposed for the three liquid argon calorimeters (84 m3 of LAr). Magnets and calorimeters will be individually tested prior to their definitive installation in a large scale cryogenic test area on the surface. The experiment is scheduled to be operational in 2005.

Eight individual racetrack coils will be assembled to form the Barrel Toroid with overall dimensions of 26 m length and 20 m diameter. In order to verify the design concept a 9 m long short version of a single Barrel Toroid coil was built. A test program was conducted at the CERN cryogenic test facility which included the evaluation of the pressure rise in the helium cooling channels during quenches of the coil. A specific experimental set-up with cold pressure transducers and capillaries was installed for online measurement of the pressure signals. In addition a computer model was used to simulate these events. The data obtained are presented.

The new calibration principle and design permits the construction of wide rang e heatmeters with precision in the range of milliwatts. The calibration function takes into account the temperature dependence of the thermal conductivity of the heatmeter material. The heat flow meas urement is, therefore, independent of the base temperature, i.e. it is also independent on the temperature drop across thermal contact between heatmeter and the cold source. The simple calibration fun ction makes the heatmeter a user-friendly portable diagnostic device. It is possible to quantify parasitic heat flow without a previous calibration, or to calibrate the heatmeter during a measurement with a specimen.

The solenoid is installed in a common cryostat of a liquid-argon calorimeter in order to minimize the mass of the cryostat wall. The coil is cooled indirectly by using two-phase helium flow in a pair of serpentine cooling line. The cryogen is supplied by the ATLAS cryogenic plant, which also supplies helium to the Toroid magnet systems. The proximity cryogenic system for the solenoid has two major components: a control dewar and a valve unit In addition, a programmable logic controller, PLC, was prepared for the automatic operation and solenoid test in Japan. This paper describes the design of the proximity cryogenic system and results of the performance test.

The cryoplants are remotely operated from several control rooms using industrial standard supervision systems, which allows the instant display of all plant data and the trends, over several days, for the most important signals. The monitoring of the cryoplant performance during transient conditions and normal operation over several months asks for a long-term recording of all plant parameters. An historical data recording system has been developed, which collects data from all cryoplants, stores them in a centralized database over a period of one year and allows an user-friendly graphical visualization. In particular, a novel tool was developed for debugging causes of plant failures by comparing selected reference data with the simultaneous evolution of all plant data. The paper describes the new system, already in operation with 11 cryoplants.

Furthermore, less accurate information is available for warm than for cold boundaries, since errors due to edge effects in small test benches increase strongly with warm boundary temperature. We establish here the thermal performance of MLI between 300 K and 77 K or 4 K, without bringing calorimetric methods into play, through the accurate measurement of a temperature profile. A cylinder in thin copper, wrapped with MLI, is cooled at one extremity while suspended under vacuum inside a sheath at room temperature. For known thermal conductivity and thickness of the tube, the heat flux can be inferred from the temperature profile. In-situ measurement of the thermal conductivity is obtained by applying a know heat flow at the warm extremity of the cylinder. Results, cross-checked with a calibrated heatmeter, compare well with what previously obtained on a large-scale measuring facility.

Between those two volumes, the busbars will pass through special feedthroughs also called lambdaplates. This article presents heat flow measurements performed on several configurations of vertical prototype lambda-plates feedthroughs. The results show that the heat flow is strongly influenced by the configuration of the busbar insulation in the saturated helium.

In the very early morning of June 7th, the coil reached the nominal operation current, 20.5 kA, and the maximum test current, 22 kA, without any problem. The electrical, thermal and mechanical behaviour of the coil was as expected and no 'strange' or abnormal phenomena were observed. Directly after a slow dump of the current, a second ramp to maximum current was performed, followed by a provoked quench (fast dump). The figure below shows the magnet current during these two ramps versus time. Several additional quenches and a steady state test were performed to complete the test. Presently the coil is at room temperature again and is being prepared for transport to point 1 (the ATLAS site) on 14 July. <P> With the successful test of the eighth coil, the on-surface test program for the Barrel Toroid coils is finished. Within one year all eight coils were successfully tested in the test station in Building 180. Dismantling of the test facility has started already. <p> <center> <img src="http://documents.cern.ch//archive/electronic/cern/others/Newsletter_article/Atlas/atl-enews-2005-005/DumpQuench.gif" alt="DumpQuench.gif" width=450> <P> <i>First ramp up to 22 kA of Barrel Toroid Coil 8 followed by a slow dump and the second ramp followed by a provoked quench.</i> </center> <p> <B>Barrel Toroid Construction in the Cavern</b> <P> Meanwhile the work in the cavern is going on as well. Seven coils have been lowered into the pit and installed. The remaining coil has already been transported from Building 180 to point 1 and the mechanical installation will be completed in August. When all the services are ready (cryogenics, vacuum, power supply, bus-bar and control and safety systems) the first test and commissioning of the Barrel Toroid can start. The start of pumping is foreseen for November 2005. Cooling down will start about one month later and in January 2006 the first powering of the Barrel Toroid is foreseen. <p> <center> <img src="http://documents.cern.ch//archive/electronic/cern/others/Newsletter_article/Atlas/atl-enews-2005-005/BT8.jpg" alt="BT8.jpg" width=450> <P><i> The 5th coil (BT8) in position; assembly of top supports and platforms starting. </i></center> <p> <center> <img src="http://documents.cern.ch//archive/electronic/cern/others/Newsletter_article/Atlas/atl-enews-2005-005/BT2.jpg" alt="BT2.jpg" width=450> <P> <i>Arrival of the 6th coil (BT2) in the cavern on 28 June.</i> </center> <p> <b>Installation of Electric Circuits</b> <P> The electric circuit includes the power supplies, breakers, resistor and diode modules and bus-bars to operate the magnets. The Barrel Toroid and the two End-Cap toroids are in one electric circuit operated at 20,500 amperes. The Central Solenoid has a separate circuit operated at 7,600 amperes to provide a 2-tesla magnetic field. <p> All circuit breakers for the toroid and solenoid are installed into the final position on level 2 of the USA15 technical cavern. The toroid power supply and the precision DCCT current meter are installed and connected to water-cooled aluminium bus-bars. Eight diode modules and three resistor modules are installed on level 3 of the USA15 technical cavern. <p> <center> <img src="http://documents.cern.ch//archive/electronic/cern/others/Newsletter_article/Atlas/atl-enews-2005-005/USA15-Lvl3.jpg" alt="USA15-Lvl3.jpg" width=450> <P> <i>Diode and resistor modules on level 3 in USA15.</i> </center> <p> The water-cooled aluminium bus-bars are an in-kind contribution of the Institute for Nuclear Physics (BINP) in Novosibirsk (Russia). All segments in USA15 have been installed by a team from BINP and CERN PH/ATI. This includes welding to connect the water cooling system and flexible copper links interconnecting the segments. Installation of the bus-bar segments in the ULX14 gallery connecting USA15 to the experimental UX15 cavern is now in progress. This requires the installation and connection of another 20 segments. The electrical circuits must be ready to use in December 2005 just before the Barrel Toroid and the Central Solenoid will be tested for the first time in the cavern. <p> <center> <img src="http://documents.cern.ch//archive/electronic/cern/others/Newsletter_article/Atlas/atl-enews-2005-005/USA15-Lvl2.jpg" alt="USA15-Lvl2.jpg" width=450> <P> <i>Installation of a bus-bar segment in USA15 level 2.</i> </center> <p> <B>Commissioning of the Cryogenics</b> <P> As we have a superconducting magnet system, the coil assemblies with a weight of some 1300 tonnes have to be cooled by liquid helium at a temperature of 4.8 kelvin (-268 degrees Celsius). The cryogenic cooling system consists of a main refrigerator and a shield refrigerator. <P> The main refrigerator is an Air Liquide machine with a liquid helium refrigeration capacity of 6kW at 4.5 K. Commissioning of this refrigerator is still in progress, but it works in very stable conditions with the complete process being under control. We have reached up to now (week 26) only two-thirds of its maximum cooling capacity, so further tuning has to be done during July and August. <P> The shield refrigerator is a Linde machine with an output of gas helium at 40 K. It has to provide two different cooling capacities, depending upon whether we use liquid nitrogen (LN2) to boost it or not. The first cooling capacity of 20kW (between 40K output and 80K return) WITHOUT the use of LN2, has already been achieved. <P> Prior to testing the second cooling capacity of 60kW (between 40K output and 80K return) WITH the use of LN2, we have to repair some heating elements on the Distribution Valve Box test-heater as they have electric shortcuts. <p> <center> <img src="http://documents.cern.ch//archive/electronic/cern/others/Newsletter_article/Atlas/atl-enews-2005-005/Linde.jpg" alt="Linde.jpg" width=450> <P><i> The Linde shield refrigerator in USA15, at floor level.</i> </center> <p> The valve boxes and storage tanks of the proximity cryogenics system have been installed in the experimental cavern. The interconnections between the different parts have been finished. At present the control system is under installation, after which it can be commissioned. <p> <center> <img src="http://documents.cern.ch//archive/electronic/cern/others/Newsletter_article/Atlas/atl-enews-2005-005/UX15-cryo.jpg" alt="UX15-cryo.jpg" width=450> <P><i> The proximity cryogenics system, valve box, storage dewar and pump cryostat (in steel) next to the distribution valve box (blue) UX15.</i> </center> <p> <B>Integration of the End-Cap Toroids has Started</b> <P> In April the last coil modules for the End-Cap Toroids were finished at the company and transported to CERN. Integration of the two cold masses, each consisting of 8 coil units and 8 keystone box supports, has now started in hall 191. Cooling lines have been prepared for and mounted onto the keystone boxes. Bimetallic Aluminium-to-Stainless-Steel transition junctions have been welded to the exits of the coil cooling lines as preparation for connection to manifolds. The mechanical preparation work of all coils and boxes has been finished and the assembly of the cold mass of End-Cap ECT-A has started. The first step is shimming to align the relative position of coils and boxes after which the units are built up around a cantilever for integration into the vacuum vessel. The cold mass integration should be ready by August and integrated with its cryostat by December. In January 2006 the testing of ECT-A can then start and a few months later it can be transported to and installed in the cavern. The second End-Cap Toroid, ECT-C, is scheduled to be completely integrated by April 2006, after which it will be tested and installed in the cavern by autumn 2006. <P> <center> <img src="http://documents.cern.ch//archive/electronic/cern/others/Newsletter_article/Atlas/atl-enews-2005-005/Keystone.jpg" alt="Keystone.jpg" width=450> <P> <i>Test assembly of the coils and keystone boxes.</i> </center> <P> <center> <img src="http://documents.cern.ch//archive/electronic/cern/others/Newsletter_article/Atlas/atl-enews-2005-005/Hall191.jpg" alt="Hall191.jpg" width=450> <P><i> The integration area and cantilever in Hall 191. </i></center> CERN EDS SzGeCERN Magnets ANAAPPR CERN Rabbers, J J CERN Ruber, R University of Uppsala Zaitsev, I Russian Institute for High Energy Physics 200507 ATLAS eNews Joleen.Pater@cern.ch n 200528 76 20050728 1042 MMD01 20050714 PUBLIC 000037330MMD ENEWSPUBLATLAS 410382 SzGeCERN 20230531152208.0 oai:cds.cern.ch:410382 cerncds:FULLTEXT cerncds:CERN:FULLTEXT INIS cerncds:CERN SPIRES 4266013 Inspire 511314 LHC-Project-Report-321 eng CERN-LHC-Project-Report-321 Balle, C Influence of Thermal Cycling on Cryogenic Thermometers 1999 Geneva CERN 1 Dec 1999 8 p paper The stringent requirements on temperature control of the superconducting magnets for the Large Hadron Collider (LHC), impose that the cryogenic temperature sensors meet compelling demands such as long-term stability, radiation hardness, readout accuracy better than 5 mK at 1.8 K and compatibility with industrial control equipment. This paper presents the results concerning long-term stability of resistance temperature sensors submitted to cryogenic thermal cycles. For this task a simple test facility has been designed, constructed and put into operation for cycling simultaneously 115 cryogenic thermometers between 300 K and 4.2 K. A thermal cycle is set to last 71/4 hours: 3 hours for either cooling down or warming up the sensors and 1 respectively 1/4 hour at steady temperature conditions at each end of the temperature cycle. A Programmable Logic Controller (PLC) drives automatically this operation by reading 2 thermometers and actuating on 3 valves and 1 heater. The first thermal cycle was accomplished in a temperature calibration facility and all the thermometers were recalibrated again after 10, 25 and 50 cycles. Care is taken in order not to expose the sensing elements to moisture that can reputedly affect the performance of some of the sensors under investigation. The temperature sensors included Allen-Bradley and TVO carbon resistors, Cernox, thin-film germanium, thin-film and wire-wound Rh-Fe sensors.

CERN Installation of the Liquid Argon Calorimater Barrel in the ATLAS Experimental Cavern <!--HTML-->On the 27th of October, the Liquid Argon Barrel cryostat was transported from Building 180 to point 1. The next day, the Barrel was lowered into the cavern, and was placed on jacks close to its final position inside the completed lower half of the Tile calorimeter. After a day of precise adjustment, it was resting within a few millimetres of its nominal final position, waiting for the upper half of the Tile calorimeter to be installed. <p> Tight requests had been issued by the Liquid Argon collaboration for the whole transport. It was foreseen that the cryostat should not see any acceleration larger than 0.15g along its axis, 0.08g transversally and 0.3g in the vertical direction. In addition, no acceleration higher than 0.03g (or even 0.003g for permanent oscillation) would be allowed at 20Hz, to avoid the risk of damaging the absorbers at this spontaneous vibration frequency. The difficulty would arise when coping these demands with the tortuous route, its slopes and curbs, vibration transmission from the engine, shocks, and of course the crane operations in SX1, the building at the ATLAS experimental site where the cryostat would be unloaded from the transport vehicle. <p> To check that these conditions were respected all along, the cryostat was instrumented with three accelerometers and one inclinometer. Also, the sixteen position monitors inside the cryostat were monitored online to check for movements of the two detector wheels and of the cryostat's cold vessel versus the warm one. Online data acquisition and distant data reading would allow immediate reaction if a dangerous situation was approached, during road transportation as well as during the descent into the cavern. Profiting from the transportation of the first Barrel Toroid coil, the whole instrumentation and data-acquisition chain had been tested one week earlier along the same route on the same trailer. <p> On D-day, the convoy, chartered from Friderici, leaves building 180 early in the morning. The cryostat, weighing 175 tons, its cold vessel and insulation vacuum vessel filled with argon, rests on two beams themselves set on damping foam, lightly chained to the platform and covered with a heavy rubber tarpaulin. Thanks to a system of independent hydraulic jacks under the four parts of the platform, the trailer takes the slope without any inclination of its platform. The first curb on the route Arago is somehow laborious, then some metres later the back wheels turn towards the centre, forcing the driver to brake. The rest of the route does not present any problem, and a small crowd of spectators can watch the slow and majestic convoy crossing the route de Meyrin. A German tourist is so impressed that, turning his head to watch the convoy, he crashes into a Y bus with his brand new BMW. The convoy arrives in front of SX1 at 2 pm, more than 5 hours after having left building 180. <p> <center> <img width=546 src="http://documents.cern.ch//archive/electronic/cern/others/Newsletter_article/Atlas/atl-enews-2004-027/OnTheRoad.jpg"> </center> <p> In SX1, the Barrel is discharged from the trailer onto jacks, then the long operation of freeing it from its supporting structure is started, correcting millimetre by millimetre any differences in axis with the 2x140-ton crane. At 11 pm the Barrel is lifted in the air and placed on jacks with its front-flange feet to permit completion of some operation on its surface, which will last some more hours into the night. <p> The next day, once several members of the collaboration have put their signature on the cryostat's body, the Barrel is lifted from the supporting jacks and starts its descent into the cavern. <P> <center> <img border="0" width=546 src="http://documents.cern.ch//archive/electronic/cern/others/Newsletter_article/Atlas/atl-enews-2004-027/descent.jpg"> </center> <p> The descent will last five hours, with a few stops to correct for the height error between the two hooks. Bringing the Barrel to rest on the jacks demands some more hours of pushing and pulling with special tooling, and then the time has come to open a champagne bottle. During all this time, acceleration and inclination have been checked with the distant data-taking chain; the embarked instrumentation will tell us that all parameters have remained well below specification along the whole route and during the descent. <P> <center> <img border="0" width=350 src="http://documents.cern.ch//archive/electronic/cern/others/Newsletter_article/Atlas/atl-enews-2004-027/InTheCavern.jpg"> </center> <p> On the 29th the final position adjustment is performed. Several hours are necessary, manoeuvering a set of hydraulic jacks which support the Barrel on the provisional "Opal" beams. Measurements from the survey team permit to know where the Barrel is sitting, before a final position correction on the A-frames is performed. At the end, the Barrel will rest with its axis nearly parallel to the Tile's axis, their centres only one mm apart. It will stay there for the next few months while the Tiles are completed around it, before being brought to its final position. <P> More pictures can be found at the following sites: <UL> <LI>Transport from Building 180 to the ATLAS site: <a href="http://atlas.web.cern.ch/Atlas/GROUPS/LIQARGON/Cryo/Cryogenics/Pictures/Barrel_Calorimeter_Transport_to_Point1/B180_to_Point1_Transport/main.htm">here</a> and <a href="http://cdsweb.cern.ch/search.py?recid=802467&ln=en">here</a>. <LI><a href="http://cdsweb.cern.ch/search.py?recid=802468&ln=en">Members of the collaboration in front of the cryostat</a>. <LI>The Barrel being lowered into the pit: <a href="http://cdsweb.cern.ch/search.py?recid=802469&ln=en">here</a> and <a href="http://atlas.web.cern.ch/Atlas/GROUPS/LIQARGON/Cryo/Cryogenics/Pictures/Barrel_Calorimeter_Transport_to_Point1/Lowering/main.htm">here</a>. <LI><a href="http://cdsweb.cern.ch/search.py?recid=802470&ln=en">The Barrel arrives in the cavern</a>. </UL> CERN EDS SzGeCERN Technical Coordination ANAAPPR CERN 200412 ATLAS eNews Joleen.Pater@cern.ch n 200450 76 20041214 1101 MMD01 20041209 PUBLIC 000034616MMD ENEWSPUBLATLAS 704507 SzGeCERN 20170921001133.0 DOI 10.1016/j.aop.2004.01.009 oai:cds.cern.ch:704507 cerncds:FULLTEXT SPIRES 5763525 Inspire 642202 oai:arXiv.org:gr-qc/0401016 http://export.arxiv.org/oai2 2015-06-25 2015-06-26T08:49:18Z true arXiv gr-qc/0401016 eng Itin, Y Is the Lorentz signature of the metric of spacetime electromagnetic in origin? 2004 6 Jan 2004 30 p Comments: Elsevier style, 30 pages, 2figures. Accepted for publication in Annals of Physics arXiv We formulate a premetric version of classical electrodynamics in terms of the excitation H and the field strength F. A local, linear, and symmetric spacetime relation between H and F is assumed. It yields, if electric/magnetic reciprocity is postulated, a Lorentzian metric of spacetime thereby excluding Euclidean signature (which is, nevertheless, discussed in some detail). Moreover, we determine the Dufay law (repulsion of like charges and attraction of opposite ones), the Lenz rule (the relative sign in Faraday's law), and the sign of the electromagnetic energy. In this way, we get a systematic understanding of the sign rules and the sign conventions in electrodynamics. The question in the title of the paper is answered affirmatively.

At all temperature levels, the static heat inleaks determine at least one third of the total heat loads in nominal operating conditions of the machine. Design validation of individual cryocomponents therefore requires a correct estimate of the heat inleaks they induce at all temperature levels, in order not to exceed the allocated heat budget. This paper illustrates the measurements of heat inleaks for several cold components of the future machine, including insulating supports, radiation shields, multi-layer insulation, instrumentation current leads. Distinct methods to determine the heat flow are chosen, depending on the expected heat loads, the temperature range spanned by the heat intercepts, and the working conditions of the component itself.

The superconducting magnet system of ATLAS is composed of the Barrel Toroid (BT), two End Caps Toroids and the Central Solenoid. The BT is formed of 8 race-track superconducting dipoles, each one 25 m long and 5 m wide. A reduced scale prototype (named B0) of one of the 8 dipoles, about one third of the length, has been constructed and tested in a dedicated cryogenic facility at CERN. To simulate the final thermal and hydraulic operating conditions, the B0 was cooled by a forced flow of 4.5 K saturated liquid helium provided by a centrifugal pump of 80 g/s nominal capacity. Both static and dynamic heat loads, generated by the induced currents on the B0 casing during a slow dump or a ramp up, have been measured to verify the expected thermal budget of the entire BT. The instrument used for the heat load measurements was a Void Fraction Meter (VFM) installed on the magnet return line. The instrument constructed at CERN was calibrated in order to provide direct readings of heat loads. An example of application of the VFM measuring method to a largescale apparatus cooled at liquid helium temperature.

All these magnets will be individually tested in an experimental area prior to their final installation in the underground cavern of the LHC collider. A dedicated cryogenic test facility has been designed and built for this purpose. It mainly consists of a 1'200 W at 4.5 K refrigerator, a 10 kW liquid nitrogen pre-cooling unit, a cryostat housing liquid helium centrifugal pumps, a distribution valve box and transfer lines. Prior to the start of the series tests of the BT magnets, two model coils are used at this facility. The first one, the so-called B00 of comparatively small size, contains the three different types of superconductors used for the ATLAS magnets which are wound on a cylindrical mandrel. The second magnet, the B0, is a reduced model of basically identical design concept as the final BT magnets. Full commissioning of all sub-systems including cryogenics, electrical powering, magnet protection and control is done ahead of the arrival of the BT series magnets. This cryogenic test facility reproduces the final thermo-hydraulic conditions in the cooling circuits of the magnets in order to validate the design concept. 7347158 20020416SLAC CERN EDS SIS INSP2002 SIS:2002 PR/LKR added CLAS1 LHC-ECR SzGeCERN Accelerators and Storage Rings ARTICLE CERN CERN LHC ATLAS INSPEC A2940T (Position sensitive detectors) INSPEC A0720M (Cryogenics) INSPEC A2970G (Energy loss and energy range relations in radiation measurement) INSPEC A2880F (Radiation monitoring and radiation protection in nuclear engineering) INSPEC B3240E (Superconducting coils and magnets) INSPEC B7420 (Particle and radiation detection and measurement) INSPEC CI N el INSPEC NI power: 1 INSPEC cooling INSPEC cryogenics INSPEC particle-calorimetry INSPEC position-sensitive-particle-detectors INSPEC radiation-monitoring INSPEC superconducting-magnets Dudarev, A Haug, F Mayri, C Orlic, J P Passardi, Giorgio Pirotte, O ten Kate, H H J LHC 1336-1338 1 IEEE Trans.

It provides a 2 tesla axial magnetic field for the inner 24 m3 volume centre particle tracker. Design and construction was done in Japan by KEK and Toshiba in collaboration with CERN. Factory tests were made in Japan with the proximity cryogenics in a geometrical arrangement corresponding to the final installation and, a full magnet test. After shipment to CERN the proximity cryogenics has been installed at a surface hall and recommissioning with load simulations and the instrumentation adapted for radiation hard requirements at the final underground area. The solenoid has recently been integrated in the common cryostat vessel of the liquid argon barrel. Cool down for final surface testing has started. The final control systems architecture and process logics are applied which is tested.

The cryogenic systems for the superconducting solenoid and focusing quadrupoles for the two LEP experiments, ALEPH and DELPHI, each supplying a cooling power of 800 W/4.5 K entropy equivalent, have accumulated more then 100'000 hours of running time. The paper summarises the 12 years cryogenic experience in the various operating modes: cool-down, steady state, recovery after energy fast dump, utilities failures and warm-up of the superconducting magnets. The detailed operation statistics is presented and compared to the other CERN cryogenic systems. Emphasis is given to the technical analysis of the fault conditions and of their consequences on the helium refrigeration production time in view of the future operation of the LHC cryogenics. 7361658 20011116SLAC CERN EDS SIS COSCI2002 SIS INSP2002 SIS:2002 PR/LKR added SIS AIP_ART2005 SIS:2005 PR/LKR added CLAS1 LHC-ECR SzGeCERN Accelerators and Storage Rings ARTICLE CERN CERN LEP XX INSPEC A0720M (Cryogenics) INSPEC A2920D (Storage rings) INSPEC B7410B (Particle beam handling and diagnostics) INSPEC B3240E (Superconducting coils and magnets) INSPEC NI power: 8 INSPEC accelerator-magnets INSPEC colliding-beam-accelerators INSPEC cryogenics INSPEC electron-accelerators INSPEC storage-rings INSPEC superconducting-magnets Dauvergne, J P Delikaris, D Passardi, Giorgio LHC 247-254 AIP Conf.

Conversely, this development has produced new challenges and markets for cryogenics, resulting in a fruitful symbiotic relation which materialized in significant technology transfer and technical progress. This began with the use of liquid hydrogen and deuterium in the targets and bubble chambers of the 1950s, 1960s and 1970s. It developed more recently with increasing amounts of liquefied noble gases - mainly argon, but also krypton and even today xenon - in calorimeters. In parallel with these applications, the availability of practical type II superconductors from the early 1960s triggered the use of superconductivity in large spectrometer magnets - mostly driven by considerations of energy savings - and the corresponding development of helium cryogenics. It is however the generalized application of superconductivity in particle accelerators - RF acceleration cavities and high-field bending and focusing magnets - which has led to the present expansion of cryogenics, with kilometer-long strings of helium-cooled devices, powerful and efficient refrigerators and superfluid helium used in high tonnage as cooling medium. This situation was well reflected over the last decades by the topical courses of the CERN Accelerator School (CAS). In 1988, CAS and DESY jointly organized the first school on Superconductivity in Particle Accelerators, held at Haus Rissen in Hamburg, where I shared the h. and duty of lecturing on cryogenics with Professor J.L. Olsen of ETH Z rich, while P. Seyfert of CEA Grenoble delivered an evening seminar on superfluidity. This successful school was reiterated in 1995, with cryogenics being addressed by Professor W.F. Vinen of University of Birmingham (superfluidity), as well as J. Schmid (thermodynamics and refrigeration) and myself (superfluid helium technology) of CERN. In the CAS School on Superconductivity and Cryogenics for Particle Accelerators and Detectors held in May 2002 in Erice, Sicily, I am particularly pleased to see a more complete syllabus in cryogenics, most of which is covered by CERN colleagues and published in this report. This is in my view, another sign of the development and vitality of this discipline at CERN, primarily in the LHC division which, by virtue of its mandate and competence, is presently building the largest helium cryogenic system in the world for the Large Hadron Collider and its experiments. I hope this report constitutes a useful source of information and updated reference for our staff dedicated to this formidable endeavour. 20021122SLAC CERN EDS CLAS1 LHC-ACR SzGeCERN Accelerators and Storage Rings CERN PREPRINT XX XX Tavian, L Vandoni, Giovanna AUTHOR|(CDS)2067499 #BEARD# Wagner, U LHC CERN Depot 4, bldg. 500-S-023 (DE4) CERN-LHC-2002-11 http://documents.cern.ch/cgi-bin/setlink?base=preprint&categ=cern&id=lhc-2002-011 Access to fulltext document http://cds.cern.ch/record/592467/files/lhc-2002-011.pdf Access to fulltext document http://cds.cern.ch/record/592467/files/lhc-2002-011.ps.gz Access to fulltext document evelyne.delucinge@cern.ch CERN n 200247 11 20100608 1158 CER01 20021121 PUBLIC 0001 002351361CER PREPRINT 708949 SzGeCERN 20200828100459.0 oai:cds.cern.ch:708949 cerncds:FULLTEXT cerncds:CERN:FULLTEXT cerncds:CERN 10.1063/1.1774678 DOI SPIRES 5835585 Inspire 647145 CERN-AT-2004-001-ECR eng Barth, K Commissioning and First Operation of the Cryogenics for the CERN Axion Solar Telescope (CAST) 2004 Geneva CERN 29 Jan 2004 8 p paper A new experiment, the CERN Axion Solar Telescope (CAST) was installed and commissioned in 2002. Its aim is to experimentally prove the existence of an as yet hypothetical particle predicted by theory as a solution of the strong CP problem and possible candidate for galactic dark matter. The heart of the detector consists of a decommissioned 10-m long LHC superconducting dipole prototype magnet, providing a magnetic field of up to 9.5 T. The whole telescope assembly is aligned with high precision to the core of the sun. If they exist, axions could be copiously produced in the core of the sun and converted into photons within the transverse magnetic field of the telescope. The converted low-energy solar axion spectrum, peaked around a mean energy of 4.4 keV, can then be focused by a special x-ray mirror system and detected by low-background photon detectors, installed on each end of the telescopes twin beam pipes. This paper describes the external and proximity cryogenic system and magnet commissioning as well as the first operational experience with the overall telescope assembly.

More recently (in the 1980s) the need of cryogenics for CERN accelerators has shown an impressive increase due to the development of superconducting accelerating cavities and high field bending magnets. Today, the two largest detectors (ATLAS and CMS) of the LHC accelerator ask for a considerable variety of cryogenic equipments and the 27 km LHC magnets ring requires the largest 1.8 K helium refrigeration and distribution systems in the world. The status of CERN cryogenics is briefly reviewed including those systems not related to the LHC complex.

If existing, axions should be copiously produced in stellar interiors and there are theoretical expectations for a low-energy axion emission spectrum peaked around a mean energy of ~ 4.4 keV. To provide the experimental proof, a solar axion telescope is at present installed at CERN, which is expected to be in total 10-12 times more efficient than the present largest set-up in operation at the University of Tokyo. The telescope will use a decommissioned 10-m long LHC superconducting dipole prototype magnet, providing a magnetic field of 9 T in operation, to catalyse the solar axion to photon conversion, which then can be detected by low-background x-ray detectors. The paper describes the external and proximity cryogenic systems and their integration into the overall telescope assembly.

The fabrication of 1600 high-field superconducting magnets operating at 1.9 K will require about 6400 km of Nb-Ti cables. A cryogenic test facility has therefore been set up in order, on the one hand, to verify the quality of individual wires and, on the other hand, to control the critical current of the assembled cables. The facility is composed of a helium liquefier, a transfer line, a dewar and pumps. The paper describes the fully automatic operation of this installation and the different test cycles applied to these wires and cables.

Complex cryoplants were installed to provide cooling at LH2 and LHe temperatures. Continuity (in the 1970s) in He cryogenics for experiments was provided by spectrometer magnets for fixed target physics of the SPS accelerator. More recently (in the 1980s), large "particle-transparent" s.c. solenoids for collider experiments (LEP) have been built demanding new cryoplants. The LHC experiments (in the 2000s) will continue the tradition with s.c. dipoles (ALICE and LHCb), solenoids (CMS, ATLAS) and toroids (ATLAS) of unusual size. Cryogenics for experiments using noble liquids follows the same trend since the development (in the 1970s) of the first shower LAr detectors. A LKr calorimeter (about 10 m3) will be operated in 1996 and the ATLAS experiment foresees a set of three huge LAr calorimeters (almost 90 m3 total volume of liquid) to be installed underground.

Among the four new experiments for the CERN Large Hadron Collider (LHC) the two largest, ATLAS and CMS, include spectrometers using 4.5 K superconducting magnets and detectors filled with liquid argon at 87 K, respectively for particle momentum and energy measurements. These detectors are of unprecedented size and complexity and the definition of the associated cryogenic systems is the result of a collaboration between CERN and several external institutes all around the world. A review of the various systems is presented with particular emphasis to the basic cooling principles, the special cryogenic features and the operation scenarios.

This is reflected in the helium and nitrogen cryogenic systems required respectively by the magnets (three large superconducting toroids and the central solenoid with 1.6 GJ stored energy) and by the argon calorimeters containing 82 m3 of liquid which can be drained into two 50 m3 dewars in case of emergency. Further coolants of 11 m3 of liquid helium and 15 m3 of liquid nitrogen are stored underground. The potential hazards of the large quantities of cryogens in underground areas require specific attention. Design, construction and quality assurance strictly follow applicable safety rules and the cryogenic process and controls are conceived to actively cope with a number of faults. In severe cases of accidental coolant loss (helium, nitrogen) or argon, detection systems produce alarms which result in the activation of emergency gas extraction. Reviews with international experts confirmed the good safety standard of the systems.

This highly complicated structure, fabricated from copper, lead, stainless steel and glass-fiber reinforced epoxy will be placed in an aluminum cryostat. The cool down process of the detector will be limited by the maximum temperature differences accepted by the composite structure so as to avoid critical mechanical stresses. A computer program simulating the cool down of the detector by calculating the local heat transfer throughout a simplified model has been developed. The program evaluates the cool down time as a function of different contact gasses filling the spaces within the detector.

1370970 eng Miele, P ATLAS magnet common cryogenic, vacuum, electrical and control systems 2004 The superconducting Magnet System for the ATLAS detector at the LHC at CERN comprises a Barrel Toroid, two End Cap Toroids and a Central Solenoid with overall dimensions of 20 m diameter by 26 m length and a stored energy of 1.6 GJ. Common proximity cryogenic and electrical systems for the toroids are implemented. The Cryogenic System provides the cooling power for the 3 toroid magnets considered as a single cold mass (600 tons) and for the CS. The 21 kA toroid and the 8 kA solenoid electrical circuits comprise both a switch-mode power supply, two circuit breakers, water cooled bus bars, He cooled current leads and the diode resistor ramp-down unit. The Vacuum System consists of a group of primary rotary pumps and sets of high vacuum diffusion pumps connected to each individual cryostat. The Magnet Safety System guarantees the magnet protection and human safety through slow and fast dump treatment. The Magnet Control System ensures control, regulation and monitoring of the operation of the magnets. The updated design, layout, development and construction of the systems, as well as the first results of prototyping and commissioning are presented. 10 Refs.

A test facility was developed to precisely determine the heat load and the mass leakage of cryogenic valves with HeII at their inlet. The temperature of the valve inlet can be varied from 1.8 K to 2 K for pressures up to 3.5 bar. The valve outlet pipe temperature can be regulated between 5 K and 20 K. The heat flow is measured with high precision using a Kapitza-resistance heatmeter and is also crosschecked by a vaporization measurement. After calibration, a precision of 10 mW for heat flows up to 1.1 W has been achieved. The helium leak can be measured up to 15 mg/s with an accuracy of 0.2 mg/s. We present a detailed description of the test facility and the measurements showing its performances.

For final validation of the industrial design with respect to heat inleaks between large surfaces at different temperatures, a full-scale test cryostat has been constructed. The facility reproduces the same pattern of temperature levels as the LHC dipole cryostat, avoiding the heat inleaks from local components like supports and feedthroughs and carefully minimizing fringe effects due to the truncated geometry of the facility with respect to the LHC cryostats serial layout. Thermal loads to the actively cooled radiation screen, operated between 50 K and 65 K, are measured by enthalpy difference along its length. At 1.9 K, the loads are obtained from the temperature difference across a superfluid helium exchanger. On the beam screen, the electrical power needed to stabilize the temperature at 20 K yields a direct reading of the heat losses. Precise in-situ calibration is achieved by subcooling the thermal screen, thereby zeroing radiative heat loads. Minimizing fringe effects has been rewarded by a high precision measurement, yielding one of the more accurate quantifications to date of an industrial application of MLI. The influence of possible openings in the thermal screen is monitored both at the 1.9 K bath and with a radiation sensitive bolometer. 20011108SLAC CERN EDS SIS COSCI2002 SIS AIP_ART2005 SIS:2005 PR/LKR added SIS ARC-PR-2007 CLAS1 LHC-PROJECT-REPORT SzGeCERN Accelerators and Storage Rings ARTICLE CERN LHCPROJECTREPORT CERN LHC Not applicable Policella, C Rieubland, Jean Michel Vandoni, Giovanna AUTHOR|(CDS)2067499 #BEARD# LHC 98-105 AIP Conf.
