[en] The Cryogenic Underground Observatory for Rare Events (CUORE) experiment search for the neutrinoless double beta decay (0νDBD) of ¹³⁰Te. The first step toward the experiment is represent by CUORE-0, a single CUORE-like tower that is operated in the former CUORICINO cryostat, to validate the assembly procedure and that will also serve as a sensitive 0νDBD experiment in its own right. The status of CUORE and CUORE-0 and their sensitivities are reported

[en] Cryogenic vibrations generated by continuously filled 1K Pots are a well known source of noise in all cryogenic experiments using dilution refrigerators. Starting from recent developments we realized a non invasive modification to the cryostat that completely eliminated vibrations, thermalizing the helium coming from the main bath at the pot temperature. We describe the new experimental setup and complete study of the phenomena

[en] Neutrinoless Double Beta Decay (0νDBD) is a rare spontaneous nuclear transition that plays a crucial role in neutrino physics as it can give information on the neutrino nature and neutrino mass scale. The experimental signature in the case of 0νDBD is in principle very clear: one should expect a peak at the transition energy of the decay in the summed two-electron energy spectrum. In spite of such characteristic, its identification is very challenging as the number of expected events is really low and the peak could be hidden by radioactive background fluctuations. I will discuss which experimental approaches can be followed to search for 0νDBD, which decay sources could be used and which are the important experimental parameters to take into account to realize a powerful 0nDBD experiment. Recently many experiments aiming to observe the 0νDBD have been proposed. The state of art, the next generation experiments and possible future scenarios in the experimental 0νDBD community will be reported.

[en] CUORE is a next generation experiment aimed at the detection of neutrinoless Double Beta Decay of the nuclide ¹³⁰Te. The experiment, which will take place in the Gran Sasso National Laboratory (Italy), will look for this rare decay using the macrobolometric technique with a prospected array of 988 detectors. Each bolometer will be constituted by a 5x5x5 cm³ TeO₂ crystal, for a total mass of about 200 kg of ¹³⁰Te, and will be maintained at a temperature of 10 mK. CUORE will probe the effective mass of the neutrino with a sensitivity of a few tens of meV. If an excess of counts are observed above background at the 2.5 MeV corresponding to the Q-value of the decay, CUORE will answer several questions that are still open in the field of neutrino physics, such as the determination of the particle's Majorana nature and of the absolute mass scale. A prototype for CUORE in Gran Sasso, named CUORICINO, has just closed after five years proving its importance as a stand-alone experiment.

[en] CUORE is a bolometric detector composed of 988 TeO₂ crystals, with a total mass of about 200 kg of ¹³⁰Te, currently under construction at Laboratori Nazionali del Gran Sasso in Italy. It will probe the neutrinoless double beta decay (0vDBD) of ¹³⁰Te, testing the neutrino nature and mass at the level relevant for exploring the inverted neutrino mass hierarchy. On the road towards CUORE, a first tower named CUORE-0, is being assembled and will be operated as an independent experiment in 2012. Detailed information on these detectors and on the expected performance are discussed.

[en] The front-end approach for the readout of two arrays of bolometric detectors is described. The first front-end is for an array of μ-bolometers, while the second is for an array of macro-bolometers. Analogies and differences in the adopted strategies are put into evidence

[en] We present measurements about the thermal parameters of our TeO₂ bolometric detectors, operated in the Gran Sasso Laboratory to search for rare events. These measurements allow us to model the detectors. We have introduced a parameter, detector figure of merit, that allows to compare the device performance

[en] The results obtained in the development of scintillating double-beta decay bolometers are presented. Several Mo and Cd based crystals were tested with the bolometric technique. Thanks to the scintillation light, the α background is easily discriminated. These results represent the first tangible demonstrating feasibility of this kind of technique

[en] CUORE is a 0.75 ton experiment to search for neutrinoless double beta decay of Te¹³⁰ using 988 TeO₂ bolometers. It aims at reaching a sensitivity on the effective neutrino mass of the order of few tens of meV. CUORICINO, a single CUORE tower running since 2003, plays an important role as a stand alone experiment and for developing the future CUORE setup. Present results already achieved and studies that are underway are here presented and discussed
