The commissioning of the CUORE experiment: the mini-tower run
CUORE is a ton-scale experiment approaching the data taking phase in Gran Sasso National Laboratory. Its primary goal is to search for the neutrinoless double-beta decay in 130Te using 988 crystals of tellurim dioxide. The crystals are operated as bolometers at about 10 mK taking advantage of one of the largest dilution cryostat ever built. Concluded in March 2016, the cryostat commissioning consisted in a sequence of cool down runs each one integrating new parts of the apparatus. The last run was performed with the fully configured cryostat and the thermal load at 4 K reached the impressive mass of about 14 tons. During that run the base temperature of 6.3 mK was reached and maintained for more than 70 days. An array of 8 crystals, called mini-tower, was used to check bolometers operation, readout electronics and DAQ. Results will be presented in terms of cooling power, electronic noise, energy resolution and preliminary background measurements
Results from the Cuore Experiment
The Cryogenic Underground Observatory for Rare Events (CUORE) is the first bolometric experiment searching for neutrinoless double beta decay that has been able to reach the 1-ton scale. The detector consists of an array of 988 TeO2 crystals arranged in a cylindrical compact structure of 19 towers, each of them made of 52 crystals. The construction of the experiment was completed in August 2016 and the data taking started in spring 2017 after a period of commissioning and tests. In this work we present the neutrinoless double beta decay results of CUORE from examining a total TeO2 exposure of 86.3kg yr, characterized by an effective energy resolution of 7.7 keV FWHM and a background in the region of interest of 0.014 counts/ (keV kg yr). In this physics run, CUORE placed a lower limit on the decay half- life of neutrinoless double beta decay of 130Te > 1.3.1025 yr (90% C. L.). Moreover, an analysis of the background of the experiment is presented as well as the measurement of the 130Te 2vo3p decay with a resulting half- life of T2 2. [7.9 :- 0.1 (stat.) :- 0.2 (syst.)] x 10(20) yr which is the most precise measurement of the half- life and compatible with previous results
CUORICINO: final results
CUORICINO, the predecessor experiment of CUORE, was operated in Gran Sasso National Laboratories in Italy and demonstrated the feasibility of CUORE. The CUORICINO detector was an array of large cubic TeO2 crystals summing up to the total mass of 40.7 kg. CUORICINO stopped the data taking in middle 2008. We present the CUORICINO detector performances and final experimental results in double beta decay, on ground and excited states of 130Te and on 120Te, together with the total data analysis that is of fundamental interest in the prediction of the expected CUORE background
Status of CUORE and results from CUORICINO
CUORE (Cryogenic Underground Observatory for Rare Events) is a ton-scale bolometric experiment for the search of Neutrinoless Double Beta Decay of 130Te. The detector, an array of 988 TeO2 crystals arranged in 19 towers, will probe the Majorana nature of neutrino in the inverted mass-hierarchy region. Currently under construction at the Underground Gran Sasso National Laboratories, Italy, the experiment is foreseen to start data taking by 2012. The feasibility of CUORE was demonstrated by the recently completed pilot experiment CUORICINO, which set a lower limit on the Double Beta Decay time of 130Te of T 1 / 2 0 ν > 3.1 × 10 24 y . The status of CUORE and the results from CUORICINO will be presented
