The Cryogenic Underground Observatory for Rare Events (CUORE) is a 1-ton scale bolometric experiment. The CUORE detector is an array of 988 TeO2 crystals arranged in a cylindrical compact structure of 19 towers. This will be by far the largest bolometric mass ever operated. These detectors need a base temperature around 10 mK in order to meet the performance specifications. To cool the CUORE detector a large cryogenic-free cryostat with five pulse tubes and one custom high-power dilution refrigerator has been designed. The cryostat (4 K refrigerator with pulse tubes) and dilution unit were first tested independently and then merged together. We report here a detailed description of the cryostat for the CUORE experiment together with the results of the validation tests done in 2014.

Abstract
The Cryogenic Underground Observatory for Rare Events (CUORE) is a 1-ton scale bolometric experiment. The CUORE detector is an array of 988 TeO2 crystals arranged in a cylindrical compact structure of 19 towers. This will be by far the largest bolometric mass ever operated. These detectors need a base temperature around 10 mK in order to meet the performance specifications. To cool the CUORE detector a large cryogenic-free cryostat with five pulse tubes and one custom high-power dilution refrigerator has been designed. The cryostat (4 K refrigerator with pulse tubes) and dilution unit were first tested independently and then merged together. We report here a detailed description of the cryostat for the CUORE experiment together with the results of the validation tests done in 2014.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
