Abstract In view of a future experiment on double beta decay we have constructed and operated for the first time a bolometric detector made with an ultrapure tellurium crystal of about 2.1 gram. With this detector we have been able to measure high energy gamma rays from various calibration sources with an energy resolution of 2% in the region of neutrinoless double beta decay. The thermal properties of tellurium at very low temperature are determined for the first time in view of the construction of larger detectors
