PheniX

The closed cycle cooler is mounted within the body of the PheniX and operates using compressed helium gas provided by the Cryodrive 3.0kW compressor, which is water-cooled. The sample stage is cooled by the conduction of heat between the sample stage and the cold stages of the Coldhead.

 

 

 

 

 

 

 

 

 

 

Note that there is no helium gas consumption in this system; the helium gas circuit in the Cryodrive/Coldhead combination is sealed. A Turbomolecular vacuum outfit is used to continuously pump the vacuum space around the PheniX internals and also the Rotating Seal to minimise unwanted heat leaks into the system.
