Cooling Capacity Upgrade at LHC P4
The LHC sectors are cooled by eight similar helium refrigerators. P4 needs more cooling capacity due to the superconducting RF. This has not limited LHC so far but would be a bottleneck for the HL-LHC era. Following conceptual studies ranging from completely new cryogenic infrastructure to partial modifications, it was decided to upgrade the existing…
