C3Or4B - Large Scale Cryogenic Systems VII: Commissioning
- Jun Dong (Fermilab)
- Greg Tatkowski
The largest cryogenic multipurpose test facility at CERN (SM18), recently significantly upgraded, provides helium refrigeration capacity for testing at nominal conditions, superconducting magnets, power links, radiofrequency (RF) cavities and the IT String (Inner Triplet) for the High Luminosity - Large Hadron Collider (HL-LHC) upgrade project, towards increased luminosity at interaction...
New superconducting magnets, many of them based on Nb3Sn technology, have been developed for the HL-LHC project, the High-Luminosity upgrade of the LHC (LHC Hadron Collider) at Interaction Points 1 and 5. These magnets require thorough testing in cryogenic conditions at 4.5 and 1.9 K before their installation into the LHC. Additionally, the HL-LHC includes high-current superconducting...
At the European Spallation Source (ESS), a 5 MW beam of 2.0 GeV proton with a nominal current of 62.5 mA driven by an accelerator will impact a tungsten wheel target at a repetition rate of 14 Hz and a pulse length of 2.86 ms. Fast neutrons produced via spallation process are moderated to cold and thermal neutrons of lower energy levels by passing through a thermal water pre-moderator and,...
