Description
SLAC National Accelerator Laboratory has upgraded to LCLS-II, featuring a 4 GeV superconducting linear accelerator composed of 37 cryomodules and two large helium refrigeration systems with a cooling capacity of 4 kW at 2.0 K. LCLS-II linear accelerator was successfully cooled from ambient temperature to 4.5 K and then to its final operating temperature of 2.0 K (31 mbar). In this paper, we describe the cool-down strategy, provide details of the 2.0 K pump-down results, and discuss the challenges faced during commissioning.
