Performance Assessment of 35 Cold Hydrodynamic Compressors for the 1.8 K Refrigeration Units of the LHC

  title={Performance Assessment of 35 Cold Hydrodynamic Compressors for the 1.8 K Refrigeration Units of the LHC},
  author={F. Millet and Serge Claudet and Gerard Ferlin},
The cooling capacity below 2 K for the superconducting magnets in the Large Hadron Collider (LHC) at CERN will be provided by eight refrigeration units of 2400 W at 1.8 K, each of them coupled to one 18 kW at 4.5 K refrigerator. The supply of the series units was linked to successful testing and acceptance of the pre‐series units delivered by the two selected vendors. The two pre‐series units were temporarily installed in a dedicated test station to validate the overall capacity and to properly…
