N2 - We developed a bolometer with a 0.5 g CdTe absorber using a high-sensitivity NTD germanium thermistor. An energy resolution of 24 keV (FWHM) is obtained for 0.66 to 1.8 MeV γ-rays. It shows a good linearity of the response in the energy range between 0.66 and 5.5 MeV. The gain is found to be stable for a period of 72 days of continuous operation and relatively insensitive to temperature changes of the refrigerator. The temperature change of the refrigerator for this period is within ± 1 mK. Since this material contains double positron emission (β+β+) nuclides 106Cd, 108Cd and 120Te, a new series of double beta decay experiments may become possible with this new method.
