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

format: conference procceeding

conference: 1991 Particle Accelerator Conference

year: 1991

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

abstract: A compact 20-MeV linac with an RF laser-driven electron gun will be used to drive a high-gain (10-cm gain length), 10.6- mu m wavelength FEL (free-electron laser) amplifier, operating in the SASE mode. Saturnus will mainly be used to study FEL physics in the high-gain regime, including start-up from noise, optical guiding, sidebands, saturation, and superradiance, with emphasis on the effects important for future short-wavelength operation of FELs. The primary magnetic flux is provided by C-shaped iron yokes, where between the poles thin blocks of neodymium-iron-boron magnets are placed to provide additional magnetic flux along the undulator axis.

title: Saturnus: the UCLA high-gain infrared FEL project

format: conference procceeding

conference: 12th International Free Electron Laser Conference

year: 1991

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

abstract: The authors present the status of Saturnus: 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, 0.5 T peak-field undulator is being built at the Kurchatov IAE. The FEL is being designed to operate primarily in the self-amplified spontaneous emission mode. They plan to study the startup from noise, optical guiding, saturation, sidebands and superradiance, with emphasis on the effects important for future short-wavelength operation of FELs. 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 saturation power of 50 MW. (10 References).
