Cryogens

The IRTF will provide all cryogen required to operate facility instrumentation. In addition, the IRTF will pay for liquid nitrogen required for visitor instruments. Visitors who require liquid helium should discuss their requirements with Lars Bergknut (bergknut@ifa.hawaii.edu; phone: 808-974-4210) well in advance of their observing run and should plan to purchase liquid helium directly with our supplier (Gaspro).
