End station refrigerator 2 cryoplant at Jefferson Lab
Year: 2024
Type: conference-paper
Abstract: The End Station Refrigerator 2 (ESR2) cryoplant will provide cryogens to three of the four experimental halls in support of 12 GeV Continuous Electron Beam Accelerator Facility (CEBAF) experimental demands. In particular, the near-future Measurement of a Lepton-Lepton Electroweak Reaction (MOLLER) experiment requires the additional capacity provided by ESR2. This new cryoplant consists of a 4.0 kW at 4.5-Kelvin cold box and a two-stage compressor system. The cold box and compressor equipment were received from the Superconducting Super Collider (SSC) project and are being refurbished to meet Jefferson Lab’s future operating needs. The ESR2 cryoplant includes a new, 50+ m long cold transfer line, bayonet-can, utility system, and control system. The paper describes the fabrication and installation challenges faced, mitigations adopted, and future work plans for the cryoplant.
