Mobile Test Bench for the LHC Cryogenic Instrumentation Crate Commissioning

The Large Hadron Collider (LHC) at CERN is a two-ring superconducting accelerator and proton-proton collider of 27 km circumference, which is in operational phase. The dipoles operate at 8.3 T, cooled by superfluid helium at 1.9 K. The operation and monitoring of the LHC require a massive amount of cryogenic instrumentation. This paper focuses on the commissioning of the cryogenic instrumentation.
