HL-LHC Helium cryogenic plants enters installation phase

By Emmanuel Monneret (CERN)

As of early June, the HL-LHC Cryogenics project reached a new important milestone with the launch of installation activities for the helium refrigeration plants. Two helium cryogenic plants—each delivering 14 kW equivalent at 4.5 K, including 3.25 kW at 1.9 K—will be installed at HL-LHC Point 1 and Point 5. These systems will deliver the cryogenic cooling capacity required for the new superconducting magnets, radiofrequency crab cavities, and cold powering systems.
