title: Design and operation of a novel, compact 20 MeV linac at UCLA

format: conference procceeding

conference: Intense Microwave and Particle Beams II

year: 1992

9 authors: P. G. Davis | G. Hairapetian | C. Joshi | Luhmann, N. C., Jr. | S. C. Hartman | S. Park | C. Pellegrini | J. B. Rosenzweig | Smolin, J. A.

abstract: A novel, compact S-band linac has been designed and is currently under construction at UCLA. It is expected to deliver high brightness, 200 A, 20 MeV electron pulses, less than 4 ps in duration from a device that is about 1 meter long. It comprises: (a) a laser photocathode driven gun that produces 4.5 MeV electron bunches from a 1/sup 1///sub 2/ cell cavity operating in the pi -mode and (b) an accelerating structure known as a plane wave transformer (PWT) designed by Swenson (1988). The design considerations of the machine and initial operating experience of the gun are discussed. The linac will be used for free electron laser, advanced accelerator research and beam-plasma experiments. (8 References).

title: The UCLA compact infrared free-electron laser

format: conference procceeding

conference: 13th International Free Electron Laser Conference

year: 1992

16 authors: J. W. Dodd | S. C. Hartman | S. Park | C. Pellegrini | J. B. Rosenzweig | D. B. Cline | G. Hairapetian | J. Kolonko | Smolin, J. A. | P. G. Davis | C. J. Joshi | Luhmann, N. C., Jr. | S. N. Ivanchenkov | A. S. Khlebnikov | Varfolomeev, A. A. | Barletta, W. A.

abstract: The authors present the status of a compact infrared free-electron laser, driven by a 20 MeV, S-band linac with a photoinjector. The 60 cm long hybrid undulator has a 1.5 cm period and a field on axis of 7.3 kG. The FEL will operate at 10.6 mu m as a high-gain amplifier, to study the high-gain FEL regime including the effects of self amplified spontaneous emission, optical guiding and saturation. The linac is the prototype of the plane-wave transformer. TDA simulation of the FEL shows a gain length of 10 cm, and a saturation power of 50 MW. (18 References).

title: Saturnus: the UCLA compact infrared free-electron laser project

format: conference procceeding

conference: Intense Microwave and Particle Beams II

year: 1991

17 authors: J. W. Dodd | F. Aghamir | W. A. Barletta | D. B. Cline | S. C. Hartman | T. C. Katsouleas | J. Kolonko | S. Park | C. Pellegrini | J. C. Terrien | P. G. Davis | C. J. Joshi | N. C. Luhmann | D. B. McDermott | S. N. Ivanchenkov | YuYu Lachin | A. A. Varfolomeev

abstract: Saturnus is an infrared FEL operating in the 10 mu m wavelength region, driven by a compact 20 MeV linac with a photoinjector, under construction at UCLA. The 1.5 cm period, 0.6 T peak field undulator is being built at the Kurchatov IAE. The FEL is designed to operate primarily in the self amplified spontaneous emission mode. The authors plan to study the start-up from noise, optical guiding, saturation, sidebands and superradiance, with emphasis on the effects important for future short wavelength operation of FEL's. The photoinjector follows closely the Brookhaven design. Electrons are injected into an accelerating section based on the plane-wave-transformer design developed by Swenson at SAIC. Simulation of the linac and FEL show a gain length of 10 cm, and a saturation power of 50 MW. (13 References).
