He Recovery


Due to ongoing shortages and rising helium prices, we purchased and began renovations for a helium recovery system in late 2019. The system began operation in early 2021 and is currently recycling the helium boil-off from five superconducting magnets in the department. The current setup delivers roughly 900 L of liquid He per year with a recovery rate of 97%.

Our helium recovery system uses a CryoMech liquid helium plant. This includes

  • an atmospheric pressure recovery bag,
  • a recovery compressor,
  • medium pressure storage tanks,
  • an automatic helium purifier,
  • a LHeP22 helium liquefaction plant with a 150 L collection dewar.

The manifolds that connect the magnets to the He collection circuit are based on the setup at Yale’s NMR facility.
