Description
The demonstration of the reliable operation of an X-band radio-frequency (RF) photoinjector with fields $\sim 0.4$~GV/m [1] on a photocathode provides a pathway to bright electron bunches. This success was enabled by powering the RF gun with short RF pulses thereby mitigating breakdowns and dark-current generation. The ~300-MW RF pulses were generated by decelerating a high-charge relativistic bunch train. This contribution summarizes ongoing activities focused on further deploying this two-Beam acceleration technique concept toward a free-electron laser demonstration at the Argonne Wakefield Accelerator with a focus on the beam dynamics and photon-generation aspects.
