abstract:	At LLNL we have been working to integrate an intense short-pulse laser with a low-emittance relativistic electron beam utilizing a 100 MeV S-band linac. This project uses a 100 TW, 35 fs laser, which is currently under development. (3 References).

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).
