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 our latest experimental results, including slice emittance measurements and longitudinal phase-space characterization of beams generated in this short-pulse, high-gradient X-band RF gun.
