Compton scattering of intense laser pulses with ultra-
relativistic electron beams has proven to be an attractive
source of high-brightness x-rays with keV to MeV ener-
gies. This type of x-ray source requires the electron beam
brightness to be comparable with that used in x-ray free-
electron lasers and laser and plasma based advanced accel-
erators. We describe the development and commissioning
of a 1.6 cell RF photoinjector for use in Compton scatter-
ing experiments at LLNL. Injector development issues such
as RF cavity design, beam dynamics simulations, emit-
tance diagnostic development, results of sputtered magne-
sium photo-cathode experiments, and UV laser pulse shap-
ing are discussed. Initial operation of the photoinjector is
described.
