3 Introduction LCLS-II Commissioning Workshop, Dec 4 & 5, 2018 Installation scope: Identifying activities and completion timelines in support of commissioning readiness for the cryoplant subsystems. Pre-commissioning: Dealing with mechanical and electrical check out and system cleanups Commissioning: Dealing with commissioning and performance of the following sub-systems Auxiliaries Helium compression 4.5 K Cold box 2 K Cold Box Operation: Dealing with operation of subsystems post handoff during commissioning of rest of the subsystem. Example, operation of rest of the cryoplant subsystems during commissioning of 2 K cold box.
