Transition to deployment phase approaching: update on project status
Impressive progress has been made across the entire collaboration, with production progress vital as we continue to progress towards deployment in the LHC tunnel. The upcoming Collaboration Meeting will be an exciting time to meet just after the start of deinstallation of the machine, to reflect on what we have achieved so far and what…

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),…

Implementation of crystal collimation of heavy ion beams for Run3 in absence of 11 T dipoles
Following the recommendation of the C&SR 2019, crystal collimation was successfully integrated in the WP5 upgrade baseline as an in-kind item to mitigate schedule issues with the 11 T dipoles which have shown potential reliability issues for long-term operation in the accelerator. A detailed investigation program is currently underway to understand the root cause of…

Report from the TCC
The HL-LHC Technical Coordination Committee has continued its work for the follow-up and evolution of the technical baseline of the project in a fully remote format. While the current restrictions still prohibit in-person meetings, the remote format has been allowed more active participation from all collaborators, which is an important asset for the current project…
