CEA-Gre Contributions to the LHC project
• Superfluid Helium as High-Field Magnet Coolant Pioneered at CEA-Grenoble in the 1970’s and Implemented in the Tore Supra Tokamak in the 1980’s
• LHC Cooling Scheme Studies & ValidationHeat Transfer Measurements & Modeling in the 1990’sDevelopment & Tests of LHC Cryogenic Components (1,8 K pump, sub-cooling heat exchangers) in the 1990’s
• Design, Specifications & Commissioning of the 1,8 K Refrigeration UnitsIndustrial Manufacturing (Air Liquide / IHI-Linde) in the 2000’s
• Alternative Cooling Architecture for the High-Luminosity Upgrade of the LHC (FP7 – HILUMI LHC Design Study)
