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.

Full Remote Alignment System qualification on the Single Component Test mock-up
By Mateusz Sosin and Hélène Mainaud Durand (CERN) Figure 1. SCT mock-up and installed FRAS sub-systems. The Full Remote Alignment System (FRAS) will be implemented on 68 components of the HL-LHC Project. As this will be a brand-new system, implemented in an accelerator for the first time. The Single Component Test (SCT) mock-up is a sophisticated…
