Update of project status
The HL-LHC project has continued to make impressive progress since the annual meeting in Genoa at the end of 2024. In particular I would like to highlight here the celebrations for the first Beam Screen being completed at CERN, the successful repair of the prototype RFD Crab Cavity cryo-module and its on-time installation in the…

LHC operational status
Figure 1: Photograph of the dispersion suppressor collimator (TCLD) installed in the dispersion suppressor region around ALICE. A standard 15m-long connection cryostat is replaced by two shorter connection cryostats and a bypass module that enables installation of a warm collimator. Since the restart of the LHC for its third operational run in 2022 (Run 3),…

Summary of the TCC Day and New Schedule as Agreed on during November Meeting in 2019
In an effort to further enhance the communication and transparency of activities having potential dependencies in terms of schedule or resources on other HL-LHC WPs, a first TCC day was organised on 12th March 2020. The meeting was also the occasion to commonly discuss all further opportunities of descoping and to assess the consequences of…

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…
