The Amorphous carbon coating in the beam screens production for the circulating beam in the cryomodules for the crab cavities is completed. 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, suppressing the formation of electron clouds that can result in the deterioration of the beam vacuum and heat loads to the cryogenic system. Coating of the 26 beam screens (14 RFD type and 12 DQW type, including 2 spares for each type), using the sputtering technique, was completed after 13 runs and they are stored and ready for installation in the cryomodules for the CRAB cavities.
