Cryostats, coolers & options

HPGe and Si(Li) detectors must be maintained at liquid nitrogen (LN2) temperatures (77K) when in use. The liquid nitrogen cryostat is the most important component in assuring reliable long term performance of these detector systems. Cryostats are also available which need minimal LN2 refilling or no LN2 at all.

Cryo-Pulse 5 Plus
Electrically Refrigerated Cryostat

The Cryo-Pulse® 5 Plus cryostat is an electrically powered cryostat for use with HPGe radiation detectors.

Cryo-Cycle™ II
Hybrid Cryostat

The Cryo-Cycle II cryostat is described as a “hybrid” cryostat because it combines the advantages of electric cooling with the reliability of liquid nitrogen.

Flanged™ Cryostats
Liquid Nitrogen Cryostat

The liquid nitrogen cryostat is the most important and least appreciated component in assuring reliable long term performance of a germanium detector system.
