The photo-injector operates with a 2.5 cell RF gun at 3 GHz, using a Cs2Te photocathode illuminated by a UV laser beam. The test bench is equipped with transverse beam diagnostic as well as a 90-degree spectrometer. A grid of 100 micrometer wide slits can be inserted for emittance measurements. The laser used to trigger the photo-emission process is a Nd:YLF system consisting of an oscillator and a preamplifier operating at 1.5 GHz and two powerful amplifier stages. The infrared radiation produced is frequency quadrupled in two stages to obtain the UV. A Pockels cell allows adjusting the length of the pulse train between 50 nanoseconds and 50 microseconds. The nominal train length for CTF3 is 1.272 microseconds (1908 bunches). The first electron beam in PHIN was produced in November 2008. In this paper, results concerning the operation of the laser system and measurements performed to characterize the electron beam are presented.

Cette puissance RF servant à alimenter dans le schéma final les cavités de l'accélérateur principal. Afin d'optimiser cette création de puissance, un compresseur de paquets d'électrons a été installé dans la ligne de test. Ce compresseur permet de réduire la longueur des paquets d'électrons après création et accélération dans le canon. Les paquets compressés sont ensuite accélérés par une cavité à fort gradient (50 MV/m) et transportés jusqu'à une cavité à 30 GHz. Des mesures de longueurs de paquets comprimés ont montré que des longueurs de 0,6 mm (rms) étaient obtenues à l'entrée de la cavité à 30 GHz pour des charges de 10 nC. La compression de paquets de charges comprises entre 2 et 17 nC a été mesurée. Des mesures d'émittances sont également effectuées pour étudier les effets transverses du compresseur de paquets sur le faisceau. L'utilisation du code PARMELA a permis la conception et l'optimisation de la chicane. Les résultats de ces simulations ont été comparés aux mesures expérimentales.

This design emerged from an updated understanding of limitations for normal conducting accelerating structures, which led to a new optimised design for the CLIC 12 GHz accelerating structure. The structure parameters and improvements in other sub-systems have resulted in a major revision of the parameters. The overall layout and efficiencies for CLIC with this updated parameter-set are presented.

Its 26 accelerating structures operate at 1.5 GHz, with a loaded gradient of 17 MV/m. A FODO lattice that wraps the accelerating structures at the beginning of the linac, followed by a succession of triplet lattices between the accelerating structures, is proposed. The large normalized transverse emittance (9200 mm.mrad rms), bunch length (5mmrms) and energy spread (7 MeV rms) of the e+ beam set constraints on the linac, in order to reach acceptable characteristics at 2.42 GeV for the injection into the predamping ring. The use of a bunch compressor at the linac entrance is an option in order to achieve good performance in both the longitudinal and transverse phase spaces. Tracking studies of both electron and positron beams in the linac have been performed and are presented.

The main objective of this JRA is to perform Research and Development on charge-production by interaction of a laser pulse with material within RF fields and improve or extend existing infrastructures. Another activity of PHIN is the coordination of the activities of various Institutes concerning photo-injectors. A brief review of the work of the eight European laboratories involved in PHIN is presented. One of these R&D topics is the construction of a photo-injector for the CLIC Test Facility (CTF3). In this context the status of CTF3 and its main goals - the demonstration of the feasibility of the key issues of the CLIC two-beam acceleration scheme - is also presented.

In particular, it addresses the efficient generation of a drive beam with the appropriate time structure of the electron bunches in order to produce high power RF pulses at a frequency of 30 GHz. This time structure requires a high bunch repetition frequency. It is obtained by successive injections of bunch trains into an isochronous ring using transversely deflecting RF structures. The major goal of the now completed first phase of CTF3 was to achieve the bunch train combination at low charge. In this paper, we give a description of the project and summarize the experimental results, with a focus on the successful bunch frequency multiplication for various factors up to five.

CLIC is based on a two-beam method, in which a high current drive beam is decelerated to produce 30 GHz RF power needed for high-gradient acceleration of the main beam running parallel to it. To demonstrate the outstanding feasibility issues of the scheme a new CLIC Test Facility, CTF3, is being constructed at CERN by an international collaboration. In its final configuration CTF3 will consist of a 150 MeV drive beam linac followed by a 42 m long delay loop and an 84 m combiner ring. The installation will include a 30 GHz high power test stand, a representative CLIC module and a test decelerator. The first part of the linac was installed and commissioned with beam in 2003. The first issue addressed was the generation and acceleration of a high-current drive beam in the "full beam loading" condition where RF power is converted into beam power with an efficiency of more than 90 %. The full beam loading operation was successfully demonstrated with the nominal beam current of 3.5 A. A variety of beam measurements have been performed, showing good agreement with expectations.

A new method, based on beam frequency spectrum analysis, was experimented to monitor this scheme. A coaxial pick-up and its read-out electronics were designed and mounted in the CTF3 ring to allow comparison of the amplitudes of five harmonics of the fundamental beam frequency (3 GHz) while combining the bunch trains. The commissioning of the monitor was a successful proof of principle for this new method, despite the short length of the bunch trains and the presence of parasitic signals associated to high-order waveguide modes propagating with the beam inside the pipe.

All collaborating institutes participated: LNF (Frascati), LAL (Orsay), RAL (Oxford), SLAC (Stanford) and Uppsala University. This year a new collaboration partner (North Western University Illinois) participated for the first time. In addition many CERN groups made important contributions. Important results from operation of the Preliminary phase - the bunch combination by a factor of 4 and 5 - were reported, an important proof of principle for the CLIC Drive Beam scheme. A highlight of the commissioning of the Initial phase was the successful operation of the accelerating structures with 100 % beam loading with nominal beam parameters. Impressive progress was reported on all activities. The design and layout studies are far advanced and very active hardware design and prototyping is going on. Series production of many components has already started. The major milestones for 2004 are the installation and commissioning of the Drive Beam Accelerator followed by the magnetic chicane and a 30 GHz high power RF test stand in the linac. For 2005 the installation of the Delay Loop is planned.

In particular, it addresses the generation of a drive beam with the appropriate time structure to produce high power RF pulses at a frequency of 30 GHz. The first major goal of CTF3 was to demonstrate at low charge the combination of successive bunch trains by RF deflectors in an isochronous ring. This bunch frequency multiplication has been successfully performed for various combination factors up to five and will be presented.

In order toobserve the bunch interleaving at each stage of this process, a new method based on frequency spectrum analysis has been developed. For this purpose, a coaxial RF pick-up and its detection system were designed and mounted in the CTF3 ring, in order to allow comparison of the amplitudes of five harmonics of the fundamental beam frequency (9, 12, 15, 18 and 21 GHz) while combining bunch trains. The commissioning of this monitor was a successful proof of principle for this new method, however with two limitations: the short length of the bunch trains and the presence of parasitic signals associated with waveguide modes propagating with the beam inside the pipe. 20030311SLAC CERN EDS CLIC-Note OA PR/LKR not found in 2008 CLAS1 CLICARCHIVE SzGeCERN Accelerators and Storage Rings n 200311 revised version number 1 submitted on 2003-03-06 16:02:26 CLIC-Note-557 26 p paper oai:cds.cern.ch:607746 cerncds:FULLTEXT cerncds:CERN:FULLTEXT cerncds:CERN 2003 Geneva CERN 28 Feb 2003 AB CERN Depot 4, bldg. 500-S-023 (DE4) CERN-OPEN-2003-013 12064 3666367 http://cds.cern.ch/record/607746/files/open-2003-013.pdf Access to fulltext document eng CERN Library CLIC-Note-0557 0001 Commissioning of a Bunch Frequency Monitor for the CTF3 Preliminary Phase 11 20100301 1604 CER01 20030306 PUBLIC 582253 SzGeCERN 20260409153146.0 oai:cds.cern.ch:582253 cerncds:FULLTEXT cerncds:REPORT cerncds:CERN:FULLTEXT cerncds:CERN CERCER 2340825 CERN annual report 2002-3.0386 SPIRES 5258014 Inspire 599196 CERN-PS-2002-074-AE CLIC-Note-542 eng CERN Library CLIC-Note-0542 CLIC-ABLE CLIC-Note-542 CERN-PS-2002-074-AE Yeremian, A D SLAC CTF3 drive-beam injector design 2002 Geneva CERN 23 Sep 2002 4 p paper Linear Colliders, New Modes of Acceleration, and Advanced Concepts The Two-Beam Accelerator concept is one of the most promising methods for producing RF power for future linear colliders. In particular it allows upgrades to multi-TeV energies. One of its challenges is the production of the high current drive beam, which as it passes through decelerating structures, produces rf power for acceleration of the main beam. These challenges must be studied at a smaller scale test facility. publication CC-BY JACoW CC-BY-4.0 © CERN 20020925SLAC Digitized by Digitra under DO XXX CERN EDS PSARCHIVE CLIC-Note PS-AE2 OA CLIC-Note SIS EPAC02-2002 CLICARCHIVE CLAS1 CERN-PS-AE2-REPORT CLICARCHIVE SzGeCERN Accelerators and Storage Rings CERN injection CERN gun CERN electron CERN ARTICLE REPORT CLIC CTF3 CERN Linear Colliders Miller, R SLAC Ruth, Ronald D SLAC Braun, Hans Heinrich CERN Geschonke, Günther CERN Groening, L CERN Rinolfi, Louis CERN Thorndahl, L CERN Wilson, Ian H CERN Zhou, F CERN PS TIFF https://digitization.web.cern.ch/29-Jul-2022/CERN-PS/CERN-PS-2002-074-AE/CERN-PS-2002-074-AE.tif 76280 805686 http://cds.cern.ch/record/582253/files/CERN-PS-2002-074-AE.pdf Fulltext Anne-Francoise.Molat-Berbiers@cern.ch CERN SLAC, Stanford n 200239 a2002 21 13 20100901 1605 CER01 20020923 492578 527 paris20020603 PUBLIC 0001 002340825CER MERGED-FROM-2833171 REPORT CLINOT ConferencePaper ARTICLE 581140 SzGeCERN 20260409143334.0 oai:cds.cern.ch:581140 cerncds:FULLTEXT cerncds:REPORT cerncds:CERN:FULLTEXT cerncds:CERN CERN annual report 2004-3.0221 SPIRES 5257980 Inspire 599193 CERN-PS-2002-071 CLIC-Note-537 CERN-PS-2002-071-AE eng CERN Library CLIC-Note-0537 CLIC-ABLE CLIC-Note-537 CERN-PS-2002-071-AE Rinolfi, Louis CERN The CLIC positron production scheme 2002 Geneva CERN 17 Sep 2002 4 p paper The CLIC (Compact Linear Collider) positron source is based on the conventional scheme, using a metal converter target and an Adiabatic Matching Device (AMD) composed of a Flux Concentrator (FC) and a constant magnetic field along the positron Pre-Injector linac.

The principle of the combination relies on the injection of short electron bunches into an isochronous ring using RF deflecting cavities. The commissioning of this facility started in September 2001, with alternating periods of installation work and beam studies. In this paper, we present the status of the facility, the first beam measurements and the next steps towards the completion of the experiment.

The gun is based on a thermionic gridded cathode and operates at 90 kV in the intensity range of 50 mA to 2A. The specific time structure of the beam is characterized by a burst of up to seven pulses of variable pulse width (4 to 10 ns) each separated by 420 ns, the revolution time of the former EPA (Electron Positron Accumulator) ring. The mechanical conception was specifically designed to be compatible with the existing front-end of the former LIL (LEP Injector Linac). We will describe the experimental results obtained with the beam on CTF3.

In the injection line, dispersion measurements were performed and showed a good agreement with the simulations. The beam was also successfully injected and accumulated in the ring, allowing preliminary measurements of the optics in two different operation modes.

The 3rd generation CLIC Test Facility (CTF3) will demonstrate the generation of the drive beam with the appropriate time structure, the extraction of 30 GHz RF power from this beam, as well as acceleration of a probe beam with 30 GHz RF cavities. The project makes maximum use of existing equipment and infrastructure of the LPI complex, which became available after the closure of LEP. In the first stage of the project, the "Preliminary Phase", the existing LIL linac and the EPA ring, both modified to suit the new requirements, are used to investigate the technique of frequency multiplication by means of interleaving bunches from subsequent trains. This report describes the design of this phase.

Paper ID MO201 Subj-class: Accelerator Physics Inspire The CLIC study of a high-energy (0.5 - 5 TeV), high-luminosity (1034 - 1035 cm-2 sec-1) e+e- linear collider is presented. Beam acceleration using high frequency (30 GHz) normal-conducting structures operating at high accelerating fields (150 MV/m) significantly reduces the length and, in consequence, the cost of the linac. Using parameters derived from general scaling laws for linear colliders, the beam stability is shown to be similar to lower frequency designs in spite of the strong wake-field dependency on frequency. A new cost-effective and efficient drive beam generation scheme for RF power production by the so-called "Two-Beam Acceleration" method is described. It uses a thermionic gun and a fully-loaded normal-conducting linac operating at low frequency (937 MHz) to generate and accelerate the drive beam bunches, and RF multiplication by funnelling in compressor rings to produce the desired bunch structure. Recent 30 GHz hardware developments and CLIC Test Facility (CTF) results are described.

CTF3 will use electron beams with an energy range adjustable from 170 MeV (3.5 A) to 380 MeV (with low current). The injector is based on a thermionic gun followed by a classical bunching system embedded in a long solenoidal field. As an alternative, an RF photo-injector is also being studied. The beam dynamics studies on how to reach the stringent beam parameters at the exit of the injector are presented. Simulations performed with the EGUN code showed that a current of 7 A can be obtained with an emittance less than 10 mm.mrad at the gun exit. PARMELA results are presented and compared to the requested beam performance at the injector exit. Sub-Harmonic Bunchers (SHB) are foreseen, to switch the phase of the bunch trains by 180 degrees from even to odd RF buckets. Specific issues of the thermionic gun and of the SHB with fast phase switch are discussed.

The rings must be isochronous, in order to preserve the bunch length and separation during the combination process (4-5 turns). A first isochronicity test has been performed in the CERN EPA (Electron Positron Accumulator) ring. The calculated isochronous lattice can be obtained by changing the strength of existing quadrupole families without hardware modifications. Measurements of the synchrotron frequency and of the beam's time structure have been made for both the normal and the isochronous lattices. Streak camera measurements of the bunch length have been used to tune the lattice around the isochronous point. The bunch length increases rapidly over a few turns in the normal case, while no appreciable bunch lengthening is observed over 50 turns in the isochronous case. A quantitative evaluation of the momentum compaction is obtained by measuring the bunch separation in a train when close to, and far from, the isochronous condition.

The energy for RF production is initially stored in a long-pulse electron beam which is efficiently accelerated to about 1.2 GeV by a fully loaded conventional, low-frequency (approx. 1 GHz) linac. The beam pulse length is twice the length of the high-gradient linac. Segments of this long pulse beam are compressed using combiner rings to create a sequence of higher peak power drive-beams with gaps between. This train of drive beams is distributed from the end of the linac in the opposite direction to the main beam down a common transport line so that each drive beam can power a section of the main linac. After a 180-degree turn, each high-current, low-energy drive beam is decelerated in low-impedance decelerator structures, and the resulting power is used to accelerate the low-current, high-energy beam in the main linac. The method discussed here seems relatively inexpensive, is very flexible, and can be used to accelerate beams for linear colliders over the entire frequency and energy range.

The energy for RF production is initially stored in a long-pulse electron beam which is efficiently accelerated to about 1.2 GeV by a fully loaded, conventional, low frequency (~1 GHz) linac. The beam pulse length is twice the length of the high-gradient linac. Segments of this long pulse beam are compressed using combiner rings to create a sequence of higher peak power drive beams with gaps in between. This train of drive beams is distributed from the end of the linac against the main beam direction down a common transport line so that each drive beam can power a section of the main linac. After a 180-degree turn, each high-current, low-energy drive beam is decelerated in low-impedance decelerator structures, and the resulti ng power is used to accelerate the low-current, high-energy beam in the main linac. The method discussed here seems relatively inexpensive is very flexible and can be used to accelerate beams for lin ear colliders over the entire frequency and energy range.

Such dama ge has been tested on a 0.3 mm thick tungsten monocrystal exposed during 6 months to the 30 Gev incident electron beam of the SLAC Linear Collider (SLC). The crystal was placed in the converter region , orientated in a random direction and received an integrated flux of e- (fluence) of 2 x 10^18 e-/mm^2. The crystal was analyzed before and after irradiation by X and Gamma diffractometry. No damage was observed, the mosaic spread remained unchanged during irradiation (0.4 mrad FWHM). Implications for use of orientated crystal as converter for positron sources of future LCs are discussed.

A new set of beam parameters has been presented at the LC 97 Workshop. Compared to the previous reference scheme for the injector complex, several major changes occurred. The two options, 0.5 TeV and 1 TeV (centre of mass), are discussed. Several issues concerning the RF gun and the associated laser, the beam loading compensation, the positron source, the damping rings and the bunch compressors are presented. This note presents the study of the new CLIC injector complex.

After four years of successful running, the experimental programme is now fully completed and all its objectives reached, particularly the generation of a high intensity drive beam with short bunches by a photo-injector, the production of 30 GHz RF power and the acceleration of a probe beam by 30 GHz structures. A summary of the CTF results and their impact on linear collider design is given. This covers 30 GHz high power testing, study of intense, short single bunches; as well as RF-Gun, photocathode and beam diagnostic developments. A second phase of the test facility (CTF2) is presently being installed to demonstrate the feasibility of the TBA scheme by constructing a fully engineered, 10 m long, test section very similar to the CLIC drive and main linacs, producing up to 480 MW of peak RF power at 30 GHz and accelerating the beam up to 320 MeV. The present status of CTF2 is reported.

This RF power is used to supply, in the final scheme, the cavities of the main linac. To optimise this power generation, a bunch compressor has been installed in the test line. This compressor shortens the electron bunches after creation and acceleration in the RF gun. The compressed bunches are then accelerated by a high gradient cavity (50 MV/m) and transported to a 30 GHz cavity. Compressed bunch length mesurements showed that lengths of 0.6 mm (rms) were obtained at the entrance of 30 GHz cavity for a 10 nC beam. Compression of electron bunches of charges between 2 and 17 nC have also been measured. Emittance measurements were done to study the transverse effects of the bunch compressor on the beam. The use of the code PARMELA allowed the design and optimisation of the chicane. The simulations results have been compared to the experimental measurements.
