The first RF dipole crab cavity cryomodule, which arrived with two major non-conformities, has now been successfully repaired and commissioned.

Amorphous carbon coating in the beam screens for the circulating beam in the cryomodules for the crab cavities: production completed

By Pedro Costa Pinto (CERN)

The non-crabbed line in the cryomodules for the HL-LHC crab cavities host a carbon-coated beam screen. This coating reduces the emission of secondary electrons from the beam screen surface.
