Description

A total of 32 Beam Position Monitors (BPMs) will be installed in the cryogenic magnet assemblies for the CERN High Luminosity Large Hadron Collider (HL-LHC) project. These BPMs of total 3 types are of challenging mechanical design and built at CERN. The complexity results from the multiple requirements that these BPMs must fulfil, including their operation in a cryogenic environment and their exposure to heat load resulting from the debris of the LHC experimental interactions. Robust design with tight and interlinked mechanical tolerances compatible with the HL-LHC beam induced prerequisites are needed to assure the long-term functionality of these BPMs. This work discusses the requirements of the cryogenic HL-LHC BPMs, including their design, multiple production steps and installation in the cryomagnet assembly.
