Abstract
At the end of2001 the Milano Double Beta Decay (MI-DBD) experiment on double beta decay of 130Te has been completed. The project Cryogenic Underground Observatory for Rare Events (CUORE), proposed as a natural extension of MI-DBD, will be a tightly packed array of1000 TeO2 bolometers, each being a cube 5cm on a side with a mass of790 g. The array will consists of25 vertical towers, arranged in a square of5 towers by 5 towers, each containing 10 layers of4 crystals. A single CUORE tower has been constructed as a smaller scale experiment called CUORICINO. The technical feasibility of CUORE is now being tested in CUORICINO, running since few weeks. The CUORICINO experiment consists of 44 TeO2 detectors 5x5x5 cm3 and 18 TeO2 detectors 3x3x6 cm3 for a total mass ofapproxim ately 41 kg. An analysis ofthe detector performances is presented together with the new limit obtained on neutrinoless double beta decay of 130Te.
