Description
(For the CUORE Collaboration) A bolometer measures the energy deposition through a corresponding temperature rise. The Cryogenic Underground Observatory for Rare Events (CUORE) is a ton scale bolometric experiment to search for neutrinoless double beta decay in 130Te. In CUORE, a single bolometer module consists of a 5X5X5 cm3 tellurium oxide crystal, a silicon heater, and one or two Neutron Transmutation Doped germanium thermistors. Running at 10 mK base temperature, the bolometer module can achieve an energy resolution of 5 keV (0.2%) at the energy region of interest of neutrinoless double beta decay. With 988 such modules, an expected background of 0.01 counts per (keV kg year), and five years of running time, CUORE will be one of the most competitive neutrinoless double beta decay experiments on the horizon.
