Description

The High Luminosity LHC project requires a flexible approach to collimator vacuum conditioning that addresses both operational vacuum performance and the maintenance constraints associated with highly radioactive equipment. This work combines outgassing studies and LHC pressure profile analyses to optimize the vacuum conditioning procedure for collimators used for betatron cleaning installed in the Long Straight Section of Point 7 (LSS7) of the LHC. The proposed approach simplifies the bake-out procedure aligning with As Low As Reasonably Achievable (ALARA) principles, reducing intervention complexity and personnel radiation exposure without compromising vacuum quality. This study was supported by the HL-LHC project.
