Abstract
TeO2 thermal detectors are being used by the Milano group to search fo r neutrinoless double beta decay of Te-130. An upper limit for neutrin oless decay half life of 2.1 x 10(22) yr at 90% CL obtained with a 334 g TeO2 detector has been previously reported. To improve the sensitiv ity of the experiment an array of twenty 340 g TeO2 crystals will be r ealised 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 ar e discussed.
