Abstract :
TeO2 thermal detectors are being used by the Milano group to search for neutrinoless double beta decay of 130Te. An upper limit for neutrinoless decay half life of 2.1 × 1022 yr at 90% CL obtained with a 334 g TeO2 detector has been previously reported.
rove the sensitivity of the experiment an array of twenty 340 g TeO2 crystals will be realised in the next future. As a first step toward the realisation of that experiment a 4 crystal detector has been tested in the Gran Sasso refrigerator. Detector performances, data acquisition and analysis are discussed.
