Design, Construction, Installation and First Commissioning Results of the LHC Cryogenic
System
The cryogenic system of the Large Hadron
S.D. Claudet (CERN)
Collider (LHC) will be, upon its completion
in 2006, the largest in the world in terms of
refrigeration capacity with 140 kW at 4.5 K, distributed superfluid helium with 25 km of superconducting magnets
below 2 K and cryogen inventory with 100 tons of Helium. The challenges involved in the design, construction and
installation, as well as the first commissioning results will be addressed in this talk. Particular mention will be made
of the problems encountered and how they were or are being solved. Perspectives for LHC will be presented. General
considerations for future large cryogenic systems will be briefly proposed.
