disclaimer DISCLAIMER
South Pole no longer supplies LHe. Please contact the South Pole S&TPS Manager if you have liquid nitrogen needs.

Various astrophysical projects at the South Pole use cryogens to reduce instrument noise. Liquid nitrogen (LNN2) is used to calibrate and liquid helium (LHe) is used to cool circuits to four degrees above absolute zero. Liquid helium is a critical part of some experiments, and it is also volatile; therefore the volume of this cryogenic fluid on station is monitored closely.
