This magnet will be aligned in a 5.3 m long inertia tube together with auxiliary magnets on each end. On the quadrupole connection end either a pair of 38 cm long octupole or trim quadrupole magnets will be mounted, on the other end there will be combined sextupole-dipole correctors with a yoke length of 1.26 m. The powering of the main quadrupoles will be assured by two pairs of copper stabilized superconducting bus-bars placed inside the cold mass next to the bus-bars for the main dipole magnets. Each of the two quadrupole apertures will be connected to its quench protection diode. The construction of three prototypes has been entrusted to the CEA/Saclay laboratory, in the frame of the special French contribution to the LHC project. The first cold mass prototype has been completed and warm-measured for its multipole content at CEA. The second cold mass is presently under completion. The paper will review the experience with the development of the quadrupole coils and cold mass construction and gives the results of the first warm magnetic measurements. An outlook for the series manufacture of the 400 arc quadrupole magnets and their cold masses for the LHC machine will complete the report. 20000313SLAC CERN EDS SIS INSP2000 6570978 SIS:2000 PR/LKR added SIS ARC-PR-2007 CLAS1 LHC-PROJECT-REPORT SzGeCERN Accelerators and Storage Rings ARTICLE CERN LHCPROJECTREPORT CERN LHC Not applicable INSPEC A2920D (Storage rings) INSPEC B7410B (Particle beam handling and diagnostics) INSPEC B3240E (Superconducting coils and magnets) INSPEC NI size: 3 INSPEC accelerator-magnets INSPEC colliding-beam-accelerators INSPEC proton-accelerators INSPEC storage-rings INSPEC superconducting-magnets Rifflet, J M AUTHOR|(CDS)2079513 #BEARD# Simon, F Tortschanoff, Theodor Védrine, P LHC 170-173 IEEE Trans.

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.

One of the design requirements was to keep the excitation current of the magnet below 6 kA in view of minimizing the costs of the powering circuits. The design of the quadrupole is based on a 8.2 mm NbTi cable, and is designed for a nominal gradient of 200 T/m at 1.9 K. In this paper we present the design of the quadrupole and discuss the construction details of the 1 m single aperture model which has been recently completed.

The paper describes a new two-coordinate measuring device, which is able to obtain scanned images of flat composite samples at liquid nitrogen temperature. The sample is cooled at 77 K into a flat quartz tray to permit the optical access to the sample from the bottom. The comparison of the images taken at room and liquid nitrogen temperatures by a high-resolution flatbed scanner gives the thermal contraction of the components.

Each of the four approved detectors (ALICE, ATLAS, CMS, and LHCb) to be installed at the interaction points of this machine relies on a sophisticated magnet system for separation and momentum measurements of the charged particles. The magnets are being designed, manufactured, tested and installed under the technical and financial responsibility of the experiment collaborations, but must satisfy constraints imposed by the laboratory, regarding in particular the cryogenics, powering, controls, and safety. The delivery and assembly schedules are also highly constrained by the requirement to have the magnet systems fully installed before the projected commissioning of the accelerator in 2005. The report will compare the salient features of these magnet systems, and of their integration into the CERN environment.

The heart of the LHC cryogenic system is the quasi-isothermal magnet cooling scheme, in which flowing two-phase saturated superfluid helium removes the heat load from the 36'000 ton cold mass, immersed in some 400 m3 static pressurised superfluid helium. The LHC also makes use of supercritical helium for non-isothermal cooling of the beam screens which intercept most of the dynamic heat loads at higher temperature. Although not used in normal operation, liquid nitrogen will provide the source of refrigeration for precooling the machine. Refrigeration for the LHC is produced in eight large refrigerators, each with an equivalent capacity of about 18 kW at 4.5 K, completed by 1.8 K refrigeration units making use of several stages of hydrodynamic cold compressors. The cryogenic fluids are distributed to the cryomagnet strings by a compound cryogenic distribution line circling the tunnel. Procurement contracts for the major components of the LHC cryogenic system have been adjudicated to industry, and their progress will be briefly reported. Besides construction proper, the study and development of cryogenics for the LHC has resulted in salient advances in several fields of cryogenic engineering, which we shall also review.

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.

It aims at detecting $\nu_{\tau}$ charged current interactions by observing the production of the $\tau$ lepton through its various decay modes by means of kinematical criteria. The detector reconstructs the event kinematics and identifies electrons, muons and photons. It uses the UA1 magnet. The target consists of 44 drift chambers, (132 sensitive planes) each 2.2% $X_{0}$thick, with a total mass of 2.9 tons over a fiducial 2.6 x 2.6 x 4 $m^{3}$. It is followed by transition radiation detectors and an electromagnetic calorimeter which includes a preshower detector. The muons are identified after the return-yoke of the magnet.

Large event to event fluctuations in the shower shape and significant energy depositions far from the incident hadron were observed making it difficult to associate all the deposited energy to the incident hadron that caused it. Since in the NOMAD detector the momenta of charged hadrons are measured by a magnetic spectrometer, such an association is necessary to be able to subtract from the calorimeter all the energy caused by the observed charged hadrons in order to avoid double counting. Probability functions based on the measurements have been developed to describe fluctuations of the lateral shower shape.\ Starting from these functions, an algorithm is developed for identifying the energy deposition associated to a charged hadron.\ The identification and separation of overlapping showers based on these functions is also discussed. The Monte Carlo simulation of the calorimeter reproduces the test beam data well therefore allowing the application of the algorithm at angles and momenta not studied in the test beam.

Wilkinson Results on L2 Trigger Reconstruction in Single and Di-Muon Topologies 09 Mar 2001 A detailed study of the CMS L2 trigger performance in single and di-muontopologies is reported, using the full detector simulation developed in CMSIM and the digitization, L1 trigger simulation and L2 reconstruction code developed in ORCA. The study was performed assuming the high luminosity scenario for the LHC machine (L= 10 nb-1s-1). The resulting single muon and di-muon rates at L2 selection level are reported and compared with the L1 Global Muon Trigger output.

Therefore a simulation program was written modeling longitudinal beam dynamics in a realistic composite linac RF system. Fast RF vector sum feedback loops control several cavities with b-dependent transit time factors driven by one transmitter. Modeling of feedback loops covers limited transmitter power and bandwidth and possible loop-delay. Vector sum calibration errors, power splitting errors and scatter in the coupling strength to the cavities are optional as well as beam loading of the pulsing beam. Different modes of mechanical cavity perturbations including Lorentz force detuning can be chosen. A multitude of phase-space representation of bunches as well as RF quantity plots are available, most of them can be assembled as a movie, showing the system dynamics in 'real time'.

Higher Order Mode (HOM) Impedance and Damping Study for the LHC Capture Cavity CERN 10 Dec 2001 6 p paper To investigate the higher order mode, HOM, damping in the LHC 200MHz ACN cavity when using four HOM couplers, simulations have been done by both 3-D frequency domain and time domain methods. These simulations have previously been used in other studies of HOM damped cavities and shown to be effective by comparing measurement and simulation results[1] [2]. Using these methods the impedance spectrum of the HOM modes in the cavity before and after damping has been obtained. From this, detailed information about the HOM coupler&#8217;s contribution to HOM damping can be obtained. The distribution and magnitude of some potentially dangerous HOM modes in the ACN cavity have been found.

Compensation of the beam induced effects CERN 11 Jun 2001 36 p paper Contribution to the CAS-RF School, Seeheim, 8-16 May 2000 The high intensity regime is reached when the voltage induced by the beam in the RF cavities is of an amplitude comparable to the desired accelerating voltage. In steady state this beam loading can be compensated by providing extra RF power. Transient beam loading occurs at injection or in the presence of a beam intensity that is not uniform around the ring. The transients are periodic at the revolution frequency. Without correction transient beam loading can be very harmful: The stable phase and bucket area will not be equal for all bunches. Strong beam loading often goes in pair with longitudinal instabilities because the RF cavities are a large contributor to the total ring impedance. The low level systems that reduce the effect of the transient beam loading will also increase the threshold intensity of the longitudinal instability caused by the cavity impedance at the fundamental RF frequency. Four classic methods are presented here: Feedforward, RF feedback, long delay feedback and bunch by bunch feedback. The first three fight against both effects: Transient beam loading and longitudinal instability, if caused by the cavity impedance (at the fundamental). The last one cures longitudinal instability (dipole mode) caused by any impedance in the machine but has no effect on the beam loading. These techniques have been made possible by the recent advent of fast digital circuitry and an emphasis will be put on the implementations.

Cost reasons suggest driving several cavities by a common transmitter, controlled over a vector sum feedback system, possibly supported by a feed forward system. Numerical simulations hint that such a system may become uncontrollable under certain conditions. In the present paper, for a model very close to reality, we will present a mathematical proof that in fact spontaneous symmetry braking is possible for these configurations, defining also the precise conditions under which it will take place. These can be used as an estimate for the real RF system stability limits. The listing of a small program demonstrating the mechanism numerically for two cavities is attached.

The low level RF system generates the drive sent to the high power equipment. It uses signals from the main bending magnet (B field) and from beam pick-ups (radial and longitudinal positions). It must minimise the beam losses and provide a beam with reproducible parameters (intensity, bunch length, average momentum and momentum spread) to either the next accelerator or the physicists. This presentation is the first of two parts: It considers the low intensity case where the voltage in the RF cavity is not influenced by the beam. The feedback loops that do not include the beam (accelerating field amplitude and cavity tuning) will not be presented.

We present a complete study of a combined system using four identical copper cavities at 200 MHz delivering 3 MV total CW voltage and having still enough bandwidth to achieve fast longitudinal damping. The shape of a cavity was designed according to the accelerating mode performance, its tuning and the higher order mode spectrum with respect to the LHC beam lines and their possible attenuation. The possibility to park the cavities during coast was included. The local heat load and the corresponding cooling water distribution as well as deformations were studied and techniques to build the cavity with all ports at low cost are proposed. The parameters of the RF generators, couplers and detuning are determined. Simulations of the total LHC RF system incorporating real delays, generator bandwidth and the control loops confirm that this system is capable of capturing and damping the beam longitudinally without losses.

SPIE 3765, "EUV, X-Ray, and Gamma-Ray Instrumentation for Astronomy X" arXiv We report on the design and laboratory testing of a prototype imaging CZT detector intended for balloon flight testing in April 2000. The detector tests several key techniques needed for the construction of large-area CZT arrays, as required for proposed hard X-ray astronomy missions. Two 10 mm x 10 mm x 5 mm CZT detectors, each with a 4 x 4 array of 1.9 mm pixels on a 2.5 mm pitch, will be mounted in a ``flip-chip'' fashion on a printed circuit board carrier card; the detectors will be placed 0.3 mm apart in a tiled configuration such that the pixel pitch is preserved across both crystals. One detector is eV Products high-pressure Bridgman CZT, and the other is IMARAD horizontal Bridgman material. Both detectors are read out by a 32-channel VA-TA ASIC controlled by a PC/104 single-board computer. A passive shield/collimator surrounded by plastic scintillator surrounds the detectors on five sides and provides a ~45 deg field of view. The background spectrum recorded by this instrument will be compared to that measured by a single-element CZT detector (10 mm x 10 mm x 2 mm high-pressure Bridgman material from eV Products) fitted with the same passive/plastic collimator but including an active BGO shield to the rear. This detector has been previously flown by us completely shielded by a passive cover. We describe preliminary laboratory results for the various systems, discuss initial background simulations, and describe our plans for balloon flight tests.

We point-out the existence of two significant drifts of the LW dark-current, one throughout the ISO mission, on a timescale of days, another within each single revolution, on a timescale of hours. We also show the existence of a dependence of the dark current on the temperature of the ISOCAM detector. By characterizing all these effects through polynomial fittings, we build a model for the LW calibration dark, that depends on the epoch of observation (parametrized with the revolution number and the time elapsed in that given revolution since the activation) and on the temperature of the ISOCAM detector. The model parameters are tuned for each of ISOCAM/LW pixel. We show that the modelling is very effective in taking into account the dark-current variations and allows a much cleaner dark subtraction than using a brute average of several calibration dark images. The residuals of the LW model-dark subtraction are, on average, similar to the pre-launch expectation.

We use semi-analytic models of galaxy formation to predict a spectral distribution for the intergalactic infrared photon field, which in turn yields information about the absorption of TeV gamma rays from extra-galactic sources. By making predictions for integral flux observations at >200 GeV for several known EGRE T sources, we directly compare our models with current observational upper limits obtained by Whipple. In addition, our predictions may offer a guide to the observing programs for the current population of TeV gamma ray observatories.

The very broad wavelength coverage (2.4-197 micron) obtained by combining observations made with the two spectrometers includes practically all of the flux emitted by the sources, and allows us to determine the emission and absorption features of the dense circumstellar dust shells. Agreement between the fluxes obtained by the two instruments is generally very good; the largest discrepancies are probably due to source variability. Our sample of oxygen-rich AGB stars exhibits a wealth of spectral features due to crystalline silicates and crystalline water ice in emission and absorption. In this study a qualitative overview of all features due to crystalline silicates and water ice in these high mass loss rate objects is presented. It seems that there is a certain onset value for the mass loss rate above which these features appear in the spectrum. Moreover, crystalline silicate emission features have been detected for the first time at wavelengths where the amorphous silicates are still in absorption, implying different spatial distributions for the two materials. A spherically symmetric and an axi-symmetric geometry are proposed.

Most standard realistic detectors lack single-photon resolution. Detector cascading always improves the resolution of any set of detectors. We introduce the confidence of an event, which quantifies the level of certainty that upon an n-fold detector coincidence in the cascade there were exactly n photons present. Although theoretically detector cascading connects detectors with single-photon resolution to standard detectors, our results suggest that currently real single-photon resolution detectors are superior to detector cascading with standard detectors.

With 34 kt of mass and in four years of data taking, this experiment will be sensitive to $\nu_\mu \to \nu_x$ oscillation with $\Delta m^2 > 6 \times 10^{-5}$ and mixing near to maximal and fully cover the region of oscillation parameters suggested by Super-Kamiokande results. Moreover, the experimental method will enable to measure the oscillation parameters from the modulation of the L/E spectrum ($\nu_\mu$ disappearance). For $\Delta m^2 > 3 \times 10^{-3}$ eV$^2$, this experiment can also establish whether the oscillation occurs into a tau or a sterile neutrino, by looking for an excess of muon-less events at high energies produced by upward-going tau neutrinos ($\nu_\tau$ appearance).

Interstellar gas within about r = 50 parsecs from the massive black hole is heated to T > 1 keV and should be visible unless thermal heating is diluted by non-thermal pressure. Since our flows are subsonic near the massive black holes, distributed cooling continues within 300 pc from the center.

In this paper, we explore the angular resolution of these two classes of detectors for two kinds of sources (essentially monochromatic compact binaries and coalescing massive-black-hole binaries) using time-domain expressions for the gravitational waveform that are accurate to 4/2 PN order. Our results display some interesting effects not previously reported in the literature, and particularly underline the importance of including the higher-order PN terms in the waveform when predicting the angular resolution of ecliptic-plane detector arrays.

This avoids the meshing of the coils and the air regions, and avoids the artificial far field boundary conditions. The method is therefore specially suited for the accurate calculation of fields in the superconducting magnets in which the field is dominated by the coil. We will present the fringe field calculations in both 2d and 3d geometries to evaluate the effect of connections and the cryostat on the field quality and the flux density to which auxiliary bus-bars are exposed. 991210SLAC CERN EDS SIS INSP2000 6570957 SIS:2000 PR/LKR added SIS ARC-PR-2007 CLAS1 LHC-PROJECT-REPORT SzGeCERN Accelerators and Storage Rings ARTICLE CERN LHCPROJECTREPORT CERN LHC Not applicable INSPEC A2920D (Storage rings) INSPEC A4110F (Steady-state electromagnetic fields; electromagnetic induction) INSPEC A0260 (Numerical approximation and analysis) INSPEC B7410B (Particle beam handling and diagnostics) INSPEC B3240E (Superconducting coils and magnets) INSPEC B5130 (Magnetic effects of electric currents) INSPEC B0290T (Finite element analysis) INSPEC accelerator-magnets INSPEC boundary-elements-methods INSPEC colliding-beam-accelerators INSPEC finite-element-analysis INSPEC magnetic-fields INSPEC proton-accelerators INSPEC storage-rings INSPEC superconducting-magnets Russenschuck, Stephan AUTHOR|(CDS)2070496 #BEARD# Siegel, N LHC 85-8 1 IEEE Trans.

Essentially a high-rate forward spectrometer, the experiment requires high accuracy tracking of scattered particles and light detectors, in order not to degrade mass resolution and particle identification. The choice of a double GEM structure with two-coordinate read-out fulfils the above requirements. Systematic studies confirm the required performances, with good safety margins for an operation in harsh environments. We discuss the design problems encountered in the construction of the large devices and the solutions adopted, together with preliminary results obtained with prototypes in the laboratory and in a high intensity beam. 991109SLAC CERN EDS CERN-EP OA SIS:200740 PR/LKR not found (from SLAC, INSPEC) SzGeCERN Detectors and Experimental Techniques CERN PREPRINT CERN SPS COMPASS NA58 Bressan, A Placci, Alfredo Ropelewski, Leszek Sauli, Fabio EP CERN ARC Library CERN-EP-99-148 http://preprints.cern.ch/cgi-bin/setlink?base=preprint&categ=cern&id=ep-99-148 Fulltext http://cds.cern.ch/record/406711/files/ep-99-148.pdf Fulltext http://cds.cern.ch/record/406711/files/ep-99-148.ps.gz Fulltext Sandrine.Sciarrino@cern.ch CERN n 199945 11 20100723 1340 CER01 19991105 329840 london990913 PUBLIC 0001 000333508CER PREPRINT ConferencePaper 406879 SzGeCERN 20180924173140.0 oai:cds.cern.ch:406879 cerncds:FULLTEXT cerncds:CERN:FULLTEXT cerncds:CERN 10.1016/S0168-9002(01)01903-9 DOI CERN annual report 2002-3.1256 SPIRES 4248180 Inspire 510040 CERN-EP-99-147 eng CERN Library EP-1999-147 ep-99-147 Sauli, Fabio Micro-pattern gas detectors 2001 Geneva CERN 11 Oct 1999 11 p paper Micro-strip gas chambers, with their excellent localization properties, high rate capability and good granularity, have been adopted by many experiments in particle physics. Two recurrent problems however have been reported: a slow degradation under sustained irradiation (or aging), and the rare but devastating occurrence of discharges. New breeds of detectors aim at improving on these crucial points, the micro-dot, CAT, micromegas, the gas electron multiplier are examples. Very performing, they are moreover robust and reliable. Two-stage devices, making use of a gas electron multiplier as first element, permit larger gains in presence of high rates and heavily ionizing tracks. Possible promising future developments in the field are outlined. 991111SLAC CERN EDS CERN-EP OA SzGeCERN Detectors and Experimental Techniques ARTICLE CERN EP CERN ARC Library CERN-EP-99-147 http://preprints.cern.ch/cgi-bin/setlink?base=preprint&categ=cern&id=ep-99-147 Fulltext http://cds.cern.ch/record/406879/files/ep-99-147.pdf Fulltext http://cds.cern.ch/record/406879/files/ep-99-147.ps.gz Fulltext Sandrine.Sciarrino@cern.ch CERN n 199945 a2002 13 20100729 1035 CER01 19991108 329840 no pagination london990913 PUBLIC 0001 000333684CER ARTICLE ConferencePaper 406880 SzGeCERN 20200828100522.0 oai:cds.cern.ch:406880 cerncds:FULLTEXT cerncds:CERN:FULLTEXT cerncds:CERN 10.1063/1.1361758 DOI CERN annual report 2001-3.1818 INSPEC 6874850 SPIRES 4248201 Inspire 510042 CERN-EP-99-149 eng CERN Library EP-1999-149 ep-99-149 Nappi, E RICH detectors 2000 Geneva CERN 10 Sep 1999 25 p paper Basic principles of the Ring Imaging CHerenkov (RICH) technique are given, the issues of designing devices based on such a technique and the factors which limit the particle discriminating power are discussed.

We stress the existence of non-tuning influences in the second mode coupling causing draggs in the frequency splittings.

In addition, the use of a low gain has the remarkable advantage of providing a reserve of photoelectrons which could be exploited by increasing the gain, in the case of a degradation of the CsI photocathodes quantum efficiency.</P></BODY> </HTML> EDMSINT200101 SzGeCERN Detectors and Experimental Techniques CERN LHC ALICE Barbosa, J DiMauro, A Morsch, A Nappi, E Paic, G Piuz, F Cozza, D DiBari, D EP Antonio.Di.Mauro@cern.ch http://documents.cern.ch/cgi-bin/setlink?base=ALICE&categ=Note&id=INT-2000-26 Fulltext 0000539ALIALI n 200163 2000 29 20040219 1414 WAI01 20010125 PUBLIC 000001119WAI DUMMY DELETED 411141 SzGeCERN 20230531152339.0 oai:cds.cern.ch:411141 cerncds:FULLTEXT cerncds:CERN:FULLTEXT INIS cerncds:CERN ITASE9 CERCER 0338635 INSPEC 6570954 SPIRES 4267389 Inspire 511441 LHC-Project-Report-340 eng CERN-LHC-Project-Report-340 Artoos, K Measurement and Analysis of Axial End Forces in a Full-Length Prototype of LHC Main Dipole Magnets 2000 Geneva CERN 1 Dec 1999 5 p paper A full-length, twin aperture prototype (MBP2N1) dipole magnet for the LHC project was assembled at CERN with collared coils delivered by industry. The design of this prototype is close to that foreseen for the dipole series manufacture as far the coil geometry and that of the yoke components are concerned. The bolts that transfer the axial magnetic forces from the coil ends to the cold mass end plates were instrumented to verify the axial coil support. These axial forces were initially measured after partial assembly, during a standard and an accelerated cool down Introduction to 1.9 K, and during magnet excitation up to 9.2 T. High force levels were observed, triggering a comparison with analytical models and measurements routinely made on 1-m single aperture dipole models. The prototype magnet was re-assembled with lower initial axial force settings and with additional instrumentation, to monitor these forces during the entire assembly process, and re-tested, to possibly correlate axial forces with training behaviour. This paper reports about the experimental observations and provides models towards their understanding 991210SLAC CERN EDS SIS INSP2000 6570954 SIS:2000 PR/LKR added SIS ARC-PR-2007 CLAS1 LHC-PROJECT-REPORT SzGeCERN Accelerators and Storage Rings ARTICLE CERN LHCPROJECTREPORT CERN LHC Not applicable INSPEC A2920D (Storage rings) INSPEC B7410B (Particle beam handling and diagnostics) INSPEC B3240E (Superconducting coils and magnets) INSPEC NI magnetic flux density: 9 INSPEC accelerator-magnets INSPEC colliding-beam-accelerators INSPEC proton-accelerators INSPEC storage-rings INSPEC superconducting-magnets Kurtyka, T Savary, F Valbuena, R Vlogaert, J LHC EST 69-72 1 IEEE Trans.

The first method, called semi-statistical, is useful for the study of the effect of single different parameters and allows the determination of the acceptable variance of the dimensions of magnet components. The second one, fully statistical, allows the study of the combined effect of many parameters. The use of these two methods allowed to evaluate with good confidence the robustness of two different dipole cross-section designs, featuring austenitic and aluminium alloy collars, respectively. 991210SLAC CERN EDS SIS INSP2000 6570956 SIS:2000 PR/LKR added SIS ARC-PR-2007 CLAS1 LHC-PROJECT-REPORT SzGeCERN Accelerators and Storage Rings ARTICLE CERN LHCPROJECTREPORT CERN LHC Not applicable INSPEC A2920D (Storage rings) INSPEC A0250 (Probability theory, stochastic processes, and statistics) INSPEC B7410B (Particle beam handling and diagnostics) INSPEC B3240E (Superconducting coils and magnets) INSPEC B0240Z (Other topics in statistics) INSPEC accelerator-magnets INSPEC colliding-beam-accelerators INSPEC proton-accelerators INSPEC statistical-analysis INSPEC storage-rings INSPEC superconducting-magnets Fessia, P Perini, D LHC 77-80 1 IEEE Trans.

In particular, inter-turn short circuits and failures of the ground insulation are well detectable when the magnet is collared, but often disappear after disassembly for repair due to the release of the pre-stress in the coils. The fault localization method presented in this paper is based on the measurement and analysis of the magnetic field generated inside the magnet aperture by a high voltage pulse. The presence of the fault modifies the distribution of the current in the coils and produces a distortion of the magnetic field. The described method aims at locating both the longitudinal and azimuthal position of the fault-affected area. The test method, the transient case FEM models and the implemented experimental set-up are presented and discussed for the LHC dipole models. 991210SLAC CERN EDS SIS INSP2000 6570977 SIS:2000 PR/LKR added SIS ARC-PR-2007 CLAS1 LHC-PROJECT-REPORT SzGeCERN Accelerators and Storage Rings ARTICLE CERN LHCPROJECTREPORT CERN LHC Not applicable INSPEC A2920D (Storage rings) INSPEC B7410B (Particle beam handling and diagnostics) INSPEC B3240E (Superconducting coils and magnets) INSPEC B2830 (Insulation and insulating coatings) INSPEC B8140 (Power system protection) INSPEC accelerator-magnets INSPEC colliding-beam-accelerators INSPEC fault-location INSPEC insulation INSPEC proton-accelerators INSPEC storage-rings INSPEC superconducting-magnets Tommasini, D LHC 166-9 1 IEEE Trans.

In case of a quench detection, protection heaters will be activated to drive the magnet to theresistive state. In addition, the magnet will be protected by a bypass diode. In order to limit quench propagation, the excitation current is ramped down at an initial rate of 113 A/s and with a time constant equal to 104 s. When a busbar quenches, its temperature must stay below safe values. Comparative measurements of a hollow and a solid busbar were performed in 1.9 K superfluid helium, 4.2 K liquid helium and 4.2 K gaseous helium during the current ramp down. We describe the experimental set-up and report the results. The development of temperatures, the quench propagation velocities as well as the residual resistance ratio (RRR) were measured. The busbar stabilized by a solid copper profile was found to be the most appropriate choice. 991210SLAC CERN EDS SIS INSP2000 6564009 SIS:2000 PR/LKR added SIS ARC-PR-2007 CLAS1 LHC-PROJECT-REPORT SzGeCERN Accelerators and Storage Rings ARTICLE CERN LHCPROJECTREPORT CERN LHC Not applicable INSPEC B3240E (Superconducting coils and magnets) INSPEC B7410B (Particle beam handling and diagnostics) INSPEC CI He el INSPEC NI temperature: 1 INSPEC accelerator-magnets INSPEC busbars INSPEC superconducting-cables INSPEC superconducting-magnets Derégel, J Henrichsen, K N Hervieu, M Juster, F P Perinet-Marquet, J L Vlogaert, J LHC 1118-21 1 IEEE Trans.

The main contributions to random errors are due to random displacements of the coil position with respect to nominal design and to the variation of the magnetization of the superconducting cable. Coil displacements can be induced either by mechanical tolerances or by the manufacturing process. Analytical and numerical scaling laws that provide the dependence of the random errors due to random displacements on the multipolar order are worked out. Both simplified and more realistic models of the coil structure are analysed. The obtained scaling laws are used to extract from experimental field shape data the amplitude of the coil displacements in the magnet prototypes. Finally, random errors due to interstrand resistance variation during the ramp are estimated 991210SLAC CERN EDS SIS INSP2000 6570959 SIS:2000 PR/LKR added SIS ARC-PR-2007 CLAS1 LHC-PROJECT-REPORT SzGeCERN Accelerators and Storage Rings ARTICLE CERN LHCPROJECTREPORT CERN LHC Not applicable INSPEC A2920D (Storage rings) INSPEC A4110D (Electrostatics, magnetostatics) INSPEC B7410B (Particle beam handling and diagnostics) INSPEC B3240E (Superconducting coils and magnets) INSPEC B5130 (Magnetic effects of electric currents) INSPEC accelerator-magnets INSPEC colliding-beam-accelerators INSPEC magnetic-fields INSPEC proton-accelerators INSPEC storage-rings INSPEC superconducting-magnets Todesco, Ezio AUTHOR|(CDS)2108516 #BEARD# Wolf, R LHC 93-7 1 IEEE Trans.

The above program, launched in summer 1998, relies on collared coils manufactured by industry and cold masses assembled at the CERN Magnet Assembly Facility. Following design, stability and robustness studies, the magnet design for series manufacture features a "6-block" coil and austenitic steel collars. A general description of the magnet with its main components is given and the main working parameters and the most important manufacturing features are presented. Results of mechanical and magnetic measurements are given as well as the performances of the first prototype. A comparison with results from the previous generation of dipole magnet models and prototypes is also made. Finally an outlook towards series manufacture is given. 991210SLAC CERN EDS SIS INSP2000 6570960 SIS:2000 PR/LKR added SIS ARC-PR-2007 CLAS1 LHC-PROJECT-REPORT SzGeCERN Accelerators and Storage Rings ARTICLE CERN LHCPROJECTREPORT CERN LHC Not applicable INSPEC A2920D (Storage rings) INSPEC B7410B (Particle beam handling and diagnostics) INSPEC B3240E (Superconducting coils and magnets) INSPEC accelerator-magnets INSPEC colliding-beam-accelerators INSPEC proton-accelerators INSPEC storage-rings INSPEC superconducting-magnets Bottura, L Fessia, P Bajko, M Modena, M Pagano, O Perini, D Savary, F Scandale, Walter AUTHOR|(CDS)2107593 #BEARD# Siemko, A Spigo, G Todesco, Ezio AUTHOR|(CDS)2108516 #BEARD# Vlogaert, J Wyss, C LHC EST 98-102 1 IEEE Trans.

Two alternatives designs, featuring common collars made out of aluminium alloy and austenitic steel, respectively, were finally compared in detail. Although both designs are almost equivalent at nominal conditions, the austenitic steel collar structure turned out to be far less sensitive to components dimensional variations.

The topics investigated in the last year include the material of the coil end spacers, the use of polyimide films from different manufacturers, the definition of optimum azimuthal and longitudinal coil pre-stress values, shimming of coil ends, collaring around the "cold bore" and different layouts of the yoke ends. This paper presents the main characteristics of such recent models, the results obtained during cold tests and the plans for the final phase of the model program for the LHC dipoles. 991210SLAC CERN EDS SIS INSP2000 6570949 SIS:2000 PR/LKR added SIS ARC-PR-2007 CLAS1 LHC-PROJECT-REPORT SzGeCERN Accelerators and Storage Rings ARTICLE CERN LHCPROJECTREPORT CERN LHC Not applicable INSPEC A2920D (Storage rings) INSPEC B7410B (Particle beam handling and diagnostics) INSPEC B3240E (Superconducting coils and magnets) INSPEC accelerator-magnets INSPEC colliding-beam-accelerators INSPEC proton-accelerators INSPEC storage-rings INSPEC superconducting-magnets Bottura, L Fessia, P Perini, D Sanfilippo, S Siegel, N Siemko, A Tommasini, D Vanenkov, I Walckiers, L Wyss, C LHC EST 49-52 1 IEEE Trans.

The dipole has a length of about 1.7 m and an aperture of 88 mm and is composed of two two-layer poles wound with NbTi cables cooled to 1.9 K to reach magnetic inductions close to 10 T. This dipole will be installed at the CERN cable test facility and used as a background field magnet to test LHC superconducting cables. In its large aperture up to four cable samples can be tested at the same time. The mechanical design of the magnet is such that coil prestress variations between warm and cold conditions are kept within 20 MPa. A short model was also built and cooled down in order to check and confirm with test results the mechanical behavior of the dipole. Magnetic measurements, at room temperature, were performed upon its arrival at CERN prior to installation in the test facility. The dipole was recently cooled down and tested. This paper will discuss the design, the main manufacturing steps and the initial test results. 991210SLAC CERN EDS SIS INSP2000 6570980 SIS:2000 PR/LKR added SIS ARC-PR-2007 CLAS1 LHC-PROJECT-REPORT SzGeCERN Accelerators and Storage Rings ARTICLE CERN LHCPROJECTREPORT CERN LHC Not applicable INSPEC A2920 (Cyclic accelerators and storage facilities) INSPEC B7410B (Particle beam handling and diagnostics) INSPEC B3240E (Superconducting coils and magnets) INSPEC B0170E (Production facilities and engineering) INSPEC CI NbTi bin, Nb bin, Ti bin INSPEC NI magnetic flux density: 1 INSPEC accelerator-magnets INSPEC superconducting-magnets INSPEC test-facilities Spigo, G Verweij, A P Boschmann, H Dubbeldam, R L González-Pelayo, J LHC 178-82 1 IEEE Trans.

We show that the most relevant effect is due to tolerances on the coil and on the internal part of the collars. The sensitivities of the field error multipoles on the mechanical tolerances are worked out using a finite element model of the dipole cross section. A MonteCarlo method is used to simulate the overall effect of both collar and coil tolerances on field quality. Correlation between random multipoles is worked out, and a comparison with the target table of the LHC field errors is given. 991210SLAC CERN EDS SIS INSP2000 6570955 SIS:2000 PR/LKR added SIS ARC-PR-2007 CLAS1 LHC-PROJECT-REPORT SzGeCERN Accelerators and Storage Rings ARTICLE CERN LHCPROJECTREPORT CERN LHC Not applicable INSPEC A2920D (Storage rings) INSPEC A0260 (Numerical approximation and analysis) INSPEC A0250 (Probability theory, stochastic processes, and statistics) INSPEC B7410B (Particle beam handling and diagnostics) INSPEC B3240E (Superconducting coils and magnets) INSPEC B0290T (Finite element analysis) INSPEC B0240G (Monte Carlo methods) INSPEC accelerator-magnets INSPEC colliding-beam-accelerators INSPEC finite-element-analysis INSPEC Monte-Carlo-methods INSPEC proton-accelerators INSPEC storage-rings INSPEC superconducting-magnets Todesco, Ezio AUTHOR|(CDS)2108516 #BEARD# Tropea, P LHC 73-6 1 IEEE Trans.

Each decapole corrector will in addition have an octupole insert (MCO) and the assembly of the two is designated MCDO. These correctors are needed in relatively large quantities, i.e. 2464 MCS Sextupoles and 1232 MCDO Decapole-Octupole assemblies. Half the number of the required spool correctors will be made in India through a collaboration between CERN and CAT (Centre for Advanced Technology, Indore, India), the other half will be built by European industry. The paper describes final choices concerning design, materials, production techniques, and testing so as to assure economic magnet manufacture but while maintaining a homogenous magnetic quality that results in a robust product. 991210SLAC CERN EDS SIS INSP2000 6570976 SIS:2000 PR/LKR added SIS ARC-PR-2007 CLAS1 LHC-PROJECT-REPORT SzGeCERN Accelerators and Storage Rings ARTICLE CERN LHCPROJECTREPORT CERN LHC Not applicable INSPEC A2920D (Storage rings) INSPEC B7410B (Particle beam handling and diagnostics) INSPEC B3240E (Superconducting coils and magnets) INSPEC accelerator-magnets INSPEC colliding-beam-accelerators INSPEC proton-accelerators INSPEC storage-rings INSPEC superconducting-magnets Bapna, S Ijspeert, Albert Karmarkar, M Karppinen, M Mazet, J Pérez, J Puntambekar, A Ruwali, K Salminen, J Thipsay, A LHC 162-5 1 IEEE Trans.

In several Large Hadron Collider single aperture dipole models, temperature profiles and temperature gradients in the magnet coil have been evaluated in the case of protection by different sets of quench heaters and different powering and protection parameters. The influence of the insulation thickness between the quench heaters and the coil has also been considered. The results show clear correlation between the positions of quench heaters, magnet protection parameters and temperature profiles. This study allowed a better understanding of the quench process mechanisms and the efficiency assessment of the different protection schemes. 991214SLAC CERN EDS SIS INSP2000 6556631 SIS:2000 PR/LKR added SIS ARC-PR-2007 CLAS1 LHC-PROJECT-REPORT SzGeCERN Accelerators and Storage Rings ARTICLE CERN LHCPROJECTREPORT CERN LHC Not applicable INSPEC A2921 (Beams in particle accelerators) INSPEC A2920D (Storage rings) INSPEC A2920L (Synchrotrons) INSPEC B7410B (Particle beam handling and diagnostics) INSPEC B3240E (Superconducting coils and magnets) INSPEC accelerator-magnets INSPEC colliding-beam-accelerators INSPEC protection INSPEC proton-accelerators INSPEC quenching-thermal INSPEC storage-rings INSPEC superconducting-magnets INSPEC synchrotrons INSPEC temperature-distribution Sanfilippo, S Siemko, A LHC 661-4 1 IEEE Trans.

The main advantage of such a fit is the extended validity range. Data available in literature and measurements on LHC strands are used to demonstrate the accuracy of the fit. The Jc data-sets used to cover a range of field from 0 T to 9 T and temperature from 1.9 K to 9 K. The standard deviation of the fits presented is of the order of 5 % or better. This accuracy is generally sufficient for design purposes, extrapolation and scaling of measured results. Better accuracy, e.g. for short sample limit prediction, can be achieved restricting the domain of validity. 991210SLAC CERN EDS SIS INSP2000 6563993 SIS:2000 PR/LKR added SIS ARC-PR-2007 CLAS1 LHC-PROJECT-REPORT SzGeCERN Accelerators and Storage Rings ARTICLE CERN LHCPROJECTREPORT CERN LHC Not applicable INSPEC A7460J (Critical currents in type-II superconductors) INSPEC A7460E (Mixed state, H/sub c/sub 2, surface sheath) INSPEC A7410 (Superconducting critical temperature, occurrence) INSPEC A7460G (Flux pinning, flux motion, fluxon-defect interactions) INSPEC B3220B (Conventional low-temperature superconducting materials) INSPEC CI NbTi bin, Nb bin, Ti bin INSPEC NI temperature: 1 INSPEC critical-current-density-superconductivity INSPEC flux-pinning INSPEC niobium-alloys INSPEC superconducting-critical-field INSPEC superconducting-transition-temperature INSPEC titanium-alloys INSPEC type-II-superconductors LHC 1054-7 1 IEEE Trans.

The magnets feature either a 5-block coil geometry or the baseline 6-block geometry foreseen for the LHC. Comparison of warm and cold measurements show that the coil geometry is essentially unchanged during cooldown. We have therefore used mechanical measurements taken on the coil and collars during assembly to estimate the azimuthal coil length. Based on these measurements we show here that the sensitivity of allowed harmonics on coil size is in good agreement with the prediction obtained from the numerical model used for designing the LHC magnets. 991210SLAC CERN EDS SIS INSP2000 6570950 SIS:2000 PR/LKR added SIS ARC-PR-2007 CLAS1 LHC-PROJECT-REPORT SzGeCERN Accelerators and Storage Rings ARTICLE CERN LHCPROJECTREPORT CERN LHC Not applicable INSPEC A2920D (Storage rings) INSPEC B7410B (Particle beam handling and diagnostics) INSPEC B3240E (Superconducting coils and magnets) INSPEC accelerator-magnets INSPEC colliding-beam-accelerators INSPEC proton-accelerators INSPEC storage-rings INSPEC superconducting-magnets Bottura, L Russenschuck, Stephan AUTHOR|(CDS)2070496 #BEARD# Siemko, A Tommasini, D Walckiers, L LHC 53-6 1 IEEE Trans.

Besides field measurements the system can be used as an antenna to localize the quench origin. The main component is a 16 m long rotating shaft, made up of 13 ceramic segments, each carrying two tangential coils plus a central radial coil, all working in parallel. The segments are connected with flexible Ti-alloy bellows, allowing the piecewise straight shaft to follow the curvature of the dipole while maintaining high torsional rigidity. At each interconnection the structure is supported by rollers and ball bearings, necessary for the axial movement for installation and for the rotation of the coil during measurement. Two such shafts are simultaneously driven by a twin-rotating unit, thus measuring both apertures of a dipole at the same time. This arrangement allows very short measurement times (typically 10 s) and is essential to perform cold magnetic measurements of all dipoles. The coil surface and direction are calibrated using a reference dipole.

Standard magnetic measurements using a coil rotating at 1 Hz do not have the time resolution required to completely resolve this phase, usually called snapback. For this reason we have developed a new and fast system dedicated to sextupole measurements. The basic component consists of three Hall plates mounted on a ring. In an ideal case this arrangement compensates the main dipole field and produces a signal proportional to the sextupole only. Mechanical tolerances and differences in the sensitivity of the Hall plates are compensated by instrumentation amplifiers and an in situ fine adjustment of the probe orientation. Using this hybrid compensation technique we have measured sextupole variations in an LHC dipole prototype during snapback at a rate of 5 Hz. In this paper we present details on the device and the results of our measurements. 991214SLAC CERN EDS SIS INSP2000 6556719 SIS:2000 PR/LKR added SIS ARC-PR-2007 CLAS1 LHC-PROJECT-REPORT SzGeCERN Accelerators and Storage Rings ARTICLE CERN LHCPROJECTREPORT CERN LHC Not applicable INSPEC A2921 (Beams in particle accelerators) INSPEC A0755 (Magnetic instruments and techniques) INSPEC A0630L (Measurement of basic electric and magnetic variables) INSPEC B3240E (Superconducting coils and magnets) INSPEC B7410B (Particle beam handling and diagnostics) INSPEC B7310L (Magnetic variables measurement) INSPEC B2560F (Bulk effect devices) INSPEC B7230 (Sensing devices and transducers) INSPEC NI frequency: 5 INSPEC accelerator-magnets INSPEC Hall-effect-transducers INSPEC magnetic-field-measurement INSPEC superconducting-magnets Larsson, L Schloss, S Schneider, M Smirnov, N Haverkamp, M LHC 1435-8 1 IEEE Trans.

For an operating gradient of 160 T/m at 4.5 K, a design based on a four layer coil wound from two graded 8.2 mm NbTi conductors has been developed. Three 1 m single aperture quadrupoles of this design have been built and successfully tested. Thereafter, the magnets have been disassembled and the coils re-collared using self-supporting collars. In this paper, we describe the design features of the twin aperture quadrupole, and report on the initial collaring tests and procedures for collaring and final assembly of the 1 m magnet. 991210SLAC CERN EDS SIS INSP2000 6570952 SIS:2000 PR/LKR added SIS ARC-PR-2007 CLAS1 LHC-PROJECT-REPORT SzGeCERN Accelerators and Storage Rings ARTICLE CERN LHCPROJECTREPORT CERN LHC Not applicable INSPEC A2920D (Storage rings) INSPEC B7410B (Particle beam handling and diagnostics) INSPEC B3240E (Superconducting coils and magnets) INSPEC CI NbTi bin, Nb bin, Ti bin INSPEC NI size: 7 INSPEC accelerator-magnets INSPEC colliding-beam-accelerators INSPEC proton-accelerators INSPEC storage-rings INSPEC superconducting-magnets Lucas, J MacKay, R S Nobes, S C Ostojic, R Treadgold, J R LHC 61-4 1 IEEE Trans.

The dipole part, used for particle orbit corrections, will be powered individually and is designed for low current, originally 30 A but now 55 A. The sextupole part, used for chromaticity corrections, is connected via cold busbars in families of 12 or 13 magnets and is powered with 550 A. Several versions of this corrector magnet were tested as model magnets in order to develop the final design for the series. In the first design the coils are nested, with the dipole coil wound around the sextupole coil to obtain as short a magnet as possible, accepting the slight cross-talk between the coils due to persistent currents, and increased saturation effects. The design has evolved and an alternative design, in which the dipole and sextupole coils are separated, is now favored. Tests at 4.5 K and at 1.9 K were conducted to determine the training behavior, the field quality, and the cross-talk between the windings. This paper discusses the results for the different configurations. 991210SLAC CERN EDS SIS INSP2000 6570975 SIS:2000 PR/LKR added SIS ARC-PR-2007 CLAS1 LHC-PROJECT-REPORT SzGeCERN Accelerators and Storage Rings ARTICLE CERN LHCPROJECTREPORT CERN LHC Not applicable INSPEC A2920D (Storage rings) INSPEC A2921 (Beams in particle accelerators) INSPEC B7410B (Particle beam handling and diagnostics) INSPEC B3240E (Superconducting coils and magnets) INSPEC NI current: 5 INSPEC accelerator-magnets INSPEC colliding-beam-accelerators INSPEC proton-accelerators INSPEC storage-rings INSPEC superconducting-magnets Arshad, S A Bajko, M Bottura, L Coxill, D Giloux, C Ijspeert, Albert Karppinen, M Landgrebe, D Walckiers, L LHC 158-61 1 IEEE Trans.
