Construction is underway with first light planned for 2020. The LCLS-II Injector section that comprises low energy from the gun up to the location of the first cryomodule is based on the LBNL Advanced Photo-Injector Experiment (APEX), and is being provided by LBNL. In 2015, responsibility for controls design and fabrication was transferred to SLAC from LBNL to promote commonality with the rest of the LCLS-II control subsystems. Collaboration between the LBNL APEX controls community and SLAC LCSL-II controls team proved vital in advancing the controls architecture toward standardized implementations integrated with the rest of LCLS-II. An added challenge was a decision to commission the injector ~1.5 years ahead of the rest of the machine, in FY 2018. This early injector commissioning (EIC) is embraced as an opportunity to gain valuable experience with the majority of the LCLS-II controls, especially the 1MHz high performance subsystems (HPS), prior to first light.
