Description
LCLSII 1-MeV CW electron source was successfully commissioned 2018-2020. 100MeV injector system is being commissioned since summer 2022. CW RF operations for injector system is routinely established and e-beam is being ramped to very high rate. Ultra-low emittance has been achieved for desired charges. Dark current along the injector beam line is systematically characterized and mitigations are placed. We will present operational experience for CW RF gun/buncher and high rate (up to 1MHz) e-beam operations. 100MeV injector beam performance including ultra-low emittance and bunch length for desired charges, and dark current measurement and mitigation will be discussed.
