Crab Cavities
First RFD cold test at TRIUMF, Canada
By Florence Thompson (CERN) and Bob Laxdal (TRIUMF)
The HiLumi Project Canadian contribution is now really kicking off.
First series cryogenic lines built for crab cavity cryomodules
By Simon Barrière (CERN)
Within the framework of the HL-LHC Work Package 4 (Crab Cavities & RF), the series production of cryogenic lines is actively underway at CERN’s EN-MME main workshop.
Successful repair and testing of the first RFD cryomodule
By Rama Calaga (CERN)
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.
