We report on the performance of an S‐band RF photocathode electron gun and accelerator for operation with the PLEIADES Thomson x‐ray source at LLNL. Simulations of beam production, transport, and focus are presented. It is shown that a 1 ps, 500 pC electron bunch with a normalized emittance of less than 5 πmm‐mrad can be delivered to the interaction point. Initial electron measurements are presented. Calculations of expected x‐ray flux are also performed, demonstrating an expected peak spectral brightness of 1020 photons/s/mm2/mrad2/0.1% bandwidth. Effects of RF phase jitter are also presented, and planned phase measurements and control methods are discussed.
