Description
Since the last comprehensive Argonne Wakefield Accelerator (AWA) report at IPAC 2017, the facility has completed several major upgrades and achieved important research milestones. Completed improvements include deployment of an EPICS control system, installation of a new laser system, and implementation of an improved laser multisplitter. Ongoing upgrades include commissioning of digital LLRF, installation of two new Canon klystrons, and development of a new drive RF photocathode gun. Upcoming improvements include upgrading the linac front end to RF-symmetrized cavities. These advances have supported an expanded research program, highlighted by record 300 MV/m gradients in a traveling-wave structure and >400 MV/m at the cathode of an X-band RF gun using short-pulse RF techniques. Current efforts in wakefield acceleration, phase-space manipulation, and high-gradient NCRF testing motivate the future AWA-II facility concept.
