First-Year Operation Overview of the SLAC LCLS-II Cryoplant

Abstract The LCLS-II, an advanced X-ray light source operated by Stanford University at SLAC for the US Department of Energy (DOE), features 37 cryomodules and a 700-meter linear accelerator (LINAC) connected to two Cryoplants, each capable of generating over 4.0 kW at 2.0 K. Commissioned in 2023, the LCLS-II Cryoplants are managed by the SLAC Cryogenic Division. This paper provides a comprehensive review of the Cryoplant’s ϐirst year of operation, covering stafϐing dynamics, budgetary considerations, and availability metrics. The insights gained from this initial year highlight critical areas for optimization and offer valuable lessons for similar cryogenic systems.
