Description
For the High-Luminosity LHC (HL-LHC) era following the third long shutdown (LS3), new generations of experimental vacuum chambers will be installed in the ATLAS, ALICE, CMS, and LHCb experiments. These chambers, located at the interaction points, ensure the required beam vacuum conditions while minimizing the impact of chamber materials on detector performance. The HL-LHC upgrade imposes tighter demands on mechanical precision, radiation tolerance, and surface quality to sustain higher luminosity and dose levels. Building on the experience gained during LS2, the LS3 designs introduce optimized materials, geometry, and production methods to meet these challenges.
This contribution outlines the main design principles, manufacturing strategies, and qualification steps guiding the development of the LS3 experimental vacuum chambers for HL-LHC operation.
