New RF Springs for HL-LHC double-beam collimators
New RF Springs for HL-LHC double-beam collimators By Lucas Hermida Pena (CERN) Collimators are Beam Interaction Devices (BIDs) designed to remove stray particles from the beam bunches which could damage sensitive equipment. Recently, two fully functional prototype double-beam collimators were fitted with new radiofrequency springs and then installed onto the assembly mock-up. In the current…

First series beam screen for the HL-LHC with amorphous carbon coating
First series beam screen for the HL-LHC with amorphous carbon coating By Florence Thompson (CERN) The first beam screen in the series for the HL-LHC has been coated with new amorphous carbon coating. This amorphous carbon coating will decrease the release of secondary electrons from the beam screen itself, avoiding the formation of electron clouds…
