Crystal collimation for the operational ion run in 2023
While the HL-LHC era for proton collisions starts in 2029 with the operational Run 4, the aim is to achieve the target HL heavy-ion performance already in Run 3 following the upgrade of the ALICE experiment during LS2. Thanks to the LHC injector upgrade program successfully completed during LS2, and in particular due to the…

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…
