A. Agafonov et al., LINAC DRIVER FOR THE FEL PROJECT AT PN-LEBEDEV-INSTITUTE, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 341(1-3), 1994, pp. 375-378
The present status of the specialized RF linac for the IR FEL project
at P.N. Lebedev Physical Institute designed for 20-25 MeV energy and u
p to 300 A peak current in 100-200 mus long train pulses is described.
The accelerator is based on the scheme of a number of independently f
ed cavities operating at 150 MHz frequency and an RF photocathode gun
with a UV laser driver with active mode synchronization. The initial p
art of the accelerator for 4 MeV has been constructed and now is under
test. Results of previous experiments with low-current test beam and
modelling of the high-current short-pulse beam behaviour are presented
.
