2 mW, 5mK CRYOGEN-FREEDILUTION RFRIGERATOR FOR THE CUORE EXPERIMENT

July 20, 2011

We have tested a new Crygen-free dilution refrigerator with two pulsed tube coolers that can circulate 8 mmol/s and has a cooling power of 2 mW at 100 mK and 3 mW at 120 mK with 5.5 mK minimum temperature. This refrigerator, now the most performing CF in the world
will be used to cool 1 ton of crystals for experiments on double beta decay for the CUORE project located in the Gran Sasso tunnel in Italy. It will also cool roughly 20 ton of Lead and Copper needed for the structure and shielding of the crystals.
