The electron gun fired its first electrons May 29, 2019. Since then, Berkeley Lab personnel have been working with their SLAC counterparts to commission the full injector source, an effort that continues so that it reaches its full performance expectations. The TTO required that it meet a set of threshold parameters en route to the final goals. The Berkeley Lab injector source for Linac Coherent Light Source-II has been formally accepted through a Transition To Operations (TTO) memorandum. The event marks the end of a highly successful multi-year effort to build this extremely challenging part of LCLS-II.
