Technical reviews of the HL-LHC Beam Dump System, the Collimation System and the Crab Cavity System
The CERN internal review of the HL-LHC Beam Dump System [BDS] took place on February 5th and was chaired by Volker Mertens. It was to a large extent triggered by two observations from the LHC beam operation towards the end of Run2, which led to the recommendation of integrating two options of the HL-LHC project…

Decision to delay the IT String test by one year and to limit the IT String test to one year operation
The HL-LHC magnets and cold powering systems are planned to be tested individually on dedicated test benches in the SM18 test facility at CERN or at the collaborators test facility (e.g. at Fermilab in the USA). The HL-LHC IT STRING will reproduce on the surface the configuration of the left side of Point 5 with…

Update on the collimator developments: first picture of the TCLD from CINEL
One important upgrade for HL-LHC is the installation of new collimators, called TCLD, in the dispersion suppressors next to IR7 and IR2. The TCLDs are needed for proton and heavy-ion operation to intercept particles that differ from the main beam in either energy or, in the case of ions, charge-to-mass ratio. In IR7, the source…
