LCLS-II Commissioning Workshop, Dec 4 & 5, 2018

3. Introduction
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.
