Description
Normal-conducting accelerating structures capable of supporting GV/m-scale electric fields offer a compelling pathway toward compact accelerator systems. Achieving such fields in photocathode RF guns is equally essential for the production of high-brightness electron bunches. Our group has recently demonstrated ~0.4 GV/m peak electric fields on the photocathode surface of an X-band (11.7 GHz) photoemission gun (Xgun) powered by ultra-short (~9 ns) RF pulses. In this work, we present the latest experimental progress, including beam characterization through slice-emittance measurements and longitudinal phase-space diagnostics. We also discuss a novel hybrid accelerating-structure design being developed for the Xgun beamline upgrade, together with ongoing and future directions toward the high-energy beam generation at the level of 100 MeV.
