CERN Detector

Liquid nitrogen cooling system

Germanium detectors nuclear physics laboratory CERN / Switzerland




Versilon™ C-210-A tubing in a permanent detector set-up at the facility at CERN, used to measure gamma radiation, which is dedicated to decay spectroscopy for research into nuclear structure, nuclear engineering and astrophysics. You can see the large 300 L liquid nitrogen dewar in the background on the left hand side. The cooling system is subjected to pressures of up to 2 bar. The tubing is in contact with liquid nitrogen inside at -196°Celcius* at room temperature outside. To reduce temperature losses during transport, the Versilon™ C-210-A Tubing is covered with an insulating foam hose.

*Please note the information on the maximum recommended operating temperature on the data sheet.
