Oral Low Level RF Workshop 2022 Superconducting RF


Andy Benwell (SLAC)


The SLAC National Accelerator Laboratory has completed the installation and checkout of RF systems for the SRF based accelerator LCLS-II, an ultra-bright Free Electron Laser. The LCLS-II is composed of 296 SRF cavities plus 2 NC cavities, each with its own LLRF control system and dedicated RF amplifier. At the time of this abstract submission, beam transport through the injector is imminent and beam through the linac is planned soon after. This LCLS-II status talk will briefly describe the RF system, summarize RF checkout, and discuss SRF commissioning of the LCLS-II linac.
