CDMS at Case Dilution Refrigerator

CDMS at Case uses a dilution refrigerator to test detectors in conditions similar to those during the data-taking-experiment in the Soudan Underground Laboratory.

The fridge is able to cool our detectors to temperatures below 20 miliKelvin (that is about -273 Celcius and .02 degreesC or K above absolute zero). The fridge is able to achieve such low temperatures by combining condensed Helium-3 and Helium-4 in a process that removes heat from these already cold materials.

A picture of the inside of the frige (left) and how it looks during operation (right) are shown below. Click on the picture to see the full-size image.
