Abstract: We report the present results of the CUORICINO experiment, a cryogenic experiment on neutrinoless Double Beta Decay (DBD) of 130Te consisting of an array of 62 TeO2 crystals with a total active mass of 40.7 kg. The array is framed inside a dilution refrigerator, heavily shielded against environmental radioactivity and high-energy neutrons, and it is operated at a temperature of 8 mK in the Gran Sasso Underground Laboratory. After several improvements the live time of the experiment is near 75%.
