A modular bolometric detector for ββ decay and dark matter searches

We present the results of the rare event searches, performed at Laboratori Nazionali del Gran Sasso, using 340 g TeO2 thermal detectors. Actually, these constitute a modular detectors of 4 crystals, that is a prototype for a near future 20 crystal detectors. The main experimental goal is to look for the 0v-Double Beta Decay of 130Te; considering only the last 1548 the low energy background spectrum was analysed for possible WTMP signals. The result on 0v-Double Beta Decay of 130Te, using 3 of the 4 crystals, gives an inferior limit on the half-time of 2.4 x 1022 y. To study the WIMPs signals the spectrum of the best performing detector was used. Lacking any evidence of WIMP interactions, limits on the spin-independent cross sections of WIMPs on Te and O nuclei have been obtained and are here reported. (authors)
