摘要：

The Cryogenic Underground Observatory for Rare Events (CUORE) will search for the 0v beta beta decay in Te-130 using a cryogenic array of TeO2 bolometers, operated at a base temperature of similar to 10 mK. CUORE will consist of a closely packed array of 19 towers each containing 52 crystals, for a total mass of 741 kg. The detector assembly is hosted in one of the largest cryostats ever constructed and will be cooled down to base temperature using a custom-built cryogen free dilution refrigerator. The CUORE cryostat along with the pulse tube based dilution refrigerator has been already commissioned at Laboratori Nazionali del Gran Sasso (LNGS) and a record base temperature, on a cubic meter scale, of r`-' 6 mK was achieved during one of the integration runs. We present the results from integration runs, characterizing the system and the cooling performance of the dilution refrigerator, effectively showcasing its stability at base temperature for the expected thermal load.
