title: A microwiggler free-electron laser at the Brookhaven Accelerator Test Facility

format: conference procceeding

conference: 11th International Free Electron Laser Conference

year: 1990

8 authors: Batchelor, K. | Ben-Zvi, I. | R. Fernow | J. Gallardo | H. Kirk | C. Pellegrini | van Steenbergen, A. | Bhowmik, A.

abstract: The authors report the design and status of an FEL experiment at the Brookhaven National Laboratory Accelerator Test Facility. A 50 MeV high-brightness electron beam will be utilized for an oscillator experiment in the visible-wavelength region. The microwiggler to be used is a superferric planar undulator with a 0.88 cm period, 60 cm length and K=0.35. The optical cavity is a 368 cm long stable resonator with broadband dielectric coated mirrors. (8 References).

title: Operational status of the Brookhaven National Laboratory Accelerator Test Facility

format: conference procceeding

conference: 1989 Particle Accelerator Conference

year: 1989

18 authors: Batchelor, K. | Ben-Zvi, I. | Biglio, I. | Chou, T. S. | R. Fernow | Fischer, J. | J. Gallardo | H. G. Kirk | Kurnit, N. | McDonald, K. T. | Palmer, R. B. | Parsa, Z. | C. Pellegrini | Sheehan, J. | Srinivasan-Rao, T. | Ulc, S. | M. Woodle | van Steenbergen, A.

abstract: The design and operation of a 50-MeV electron linear accelerator utilizing a low emittance ( gamma epsilon =5 to 10 mm-mrad) radio-frequency gun operating at an output energy of 5 MeV and a charge of 1 nC are described. Design calculations, early radio-frequency measurements, and operational experience with the electron gun utilizing a dummy cathode in place of the proposed photocathode emitter are given. The dynamics of the electron beam coming off the photocathode has been modeled with the programs PARMELA and MASK. General agreement as to the expected characteristics of the electron beam at the RF-gun exit has been obtained using the two programs. It was also verified that, with proper matching of the transverse beam, no increase of the transverse normalized emittance occurs at the linac due to the fundamental RF mode. (5 References).
