First HL-LHC Beam Position Monitor ready for installation
This May, the first Beam Position Monitor (BPM) for the HL-LHC finished its in-house production in the CERN ateliers. The BPM is now ready for assembly with the new beam screen and will be installed in the first HL-LHC Inner Triplet cryomagnet (Q1).

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 LHC, all collimators are single-beam, but these…

Robotic solution: successful preparation of the CMS rotating shielding for future HL-LHC vacuum module installation
The CMS rotating shielding has now been successfully modified in-situ to prepare it to receive new vacuum modules for the HL-LHC, using a specifically designed method to deal with the space and radiation constraints of this complex manoeuvre.
