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.

First series beam screen for the HL-LHC with amorphous carbon coating
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 and therefore reducing the heat load to the cryogenic system as much as possible.
