Manufacturing and installation of the compound cryogenic distribution line for the Large Hadron Collider.

Author(s) : BARBIER B., BOUILLOT A., BRODZINSKI K., et al.

Summary

The Large Hadron Collider (LHC) at CERN makes use of superconducting magnets operating in superfluid helium below 2 K. A compound cryogenic distribution line (QRL) feeds with helium at different temperatures and pressures the local elementary cooling loops in the cryomagnet strings. Low heat inleak to all temperature levels is essential for the overall LHC cryogenic performance. Following a competitive tendering, CERN adjudicated in 2001 the contract for the series line to Air Liquide (France). This paper recalls the main features of the technical specification and shows the project status. The basic choices and achievements for the industrialization phase of the series production are also presented, as well as the installation issues and status.
