The refrigerator operates on the Gifford-McMahon cycle that utilizes high-pressure helium from the compressor and expands it in two stages to produce cryogenic temperatures at the pump arrays. The actual temperatures produced depend on the thermal and gas loads imposed and the pump configuration that is paired up with a compressor.
The normal temperature range for the first stage is 60 to 80 degrees Kelvin and 10 to 20 degrees Kelvin for the second stage. The refrigerator consists of an actuator and a two-stage displacer operated by an electric stepper motor. 99.999% purity helium is the working gas in the system.
