Description
Two TeO2 crystal bolometers of 1.3kg each, the largest single crystals ever operated with this technique, have been successfully realized and tested below 10mK, in a dilution refrigerator located deep underground in the Gran Sasso National Laboratories. The calibration spectrum, obtained using an external 232Th γ-ray source, shows an energy resolution of 3-4keV FWHM from 0.5 to 2.6MeV, for both detectors. In the α region, a 4.3keV FWHM resolution has been observed on the 5407keV peak due to the α decay of 210Po, a natural contaminant of TeO2 crystals
