title: A millimeter wave FEL driven by a photocathode RF linac

format: conference procceeding

conference: 15th International Free Electron Laser Conference

year: 1994

11 authors: Zhang, R. | C. Pellegrini | J. B. Rosenzweig | G. LeSage | F. Hartemann | D. McDermott | C. Joshi | N. Luhmann | P. Pierini | de Salvo, L. | Bonifacio, R.

abstract: We present the design of a millimeter wave FEL based on the UCLA photocathode RF linac. The linac energy can be varied between 5 and 18 MeV. The electron pulse duration is 2 ps FWHM, with a peak current exceeding 150 A. The FEL is designed to operate in the high-gain Compton regime, controlling the slippage with the propagating radiation in a waveguide. The design permits the exploration of the basic FEL physics in this regime, including the exploration of saturation and lethargy in the superradiant and steady state regime. (15 References).

title: Photocathode driven linac at UCLA for FEL and plasma wakefield acceleration experiments

format: conference procceeding

conference: 1991 Particle Accelerator Conference

year: 1991

17 authors: S. Hartman | F. Aghamir | Barletta, W. | D. B. Cline | J. Dodd | T. Katsouleas | J. Kolonko | S. Park | C. Pellegrini | J. B. Rosenzweig | Smolin, J. | Terrien, J. | J. Davis | G. Hairapetian | C. Joshi | N. Jr. Luhmann | D. McDermott

abstract: The UCLA compact 20-MeV/c electron linear accelerators is designed to produce a single electron bunch with a peak current of 200 A, an RMS energy spread of 0.2% or less, and a short 1.2-ps RMS pulse duration. The linac is also designed to minimize emittance growth down the beamline so as to obtain emittances on the order of 8 pi mm-mrad in the experimental region. The linac will feed two beamlines, the first will run straight into the undulator for FEL experiments while the second will be used for diagnostics, longitudinal bunch compression and other electron beam experiments. A description is given of the considerations that went into the design of the accelerating structures and the transport to the experimental areas. (8 References).

title: The UCLA IR-FEL

format: conference procceeding

conference: 1990 IEEE International Conference on Plasma Science

year: 1990

11 authors: F. Aghamir | Barletta, W. | D. B. Cline | J. Dodd | S. Hartman | C. Joshi | J. Kolonko | N. Luhmann | D. McDermott | C. Pellegrini | Terrien, C.

abstract: A high-brightness RF gun operating at 2.856 GHz is being used as the injector for an IR-FEL (free-electron laser) experiment. The RF gun consists of a disk loaded, 1.5 cell cavity and a photocathode in the end wall of the cavity. A strong electric field within the half cell near the photocathode quickly accelerates the electrons, thus preventing emittance blow-up. The photocathode is to be driven by a Nd:YAG laser system producing a 10-ps pulse. The power for the RF gun will be supplied by a 25-MW klystron. The RF power is coupled to the cavity via an S-band waveguide attached to the sidewall of the gun. The TE_10 mode excited in the waveguide strongly couples to the pi-mode with the RF gun while the zero mode is suppressed. (0 References).
