LABORATORI NAZIONALI DEL GRAN SASSO
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. After the completion of the experiment construction, CUORE was then successfully cooled down to a base temperature below 8 mK by the beginning of 2017. After few months devoted to the initial detector commissioning, calibrations started in April 2017 followed by a physics run in May 2017. A new campaign of optimization of the detector performance is now ongoing to be followed by a new physics run during the summer. The CUORE cryogenic setup and the system performances will be reported. Moreover the first physics results of CUORE, as well as a summary of the initial detector performances will be presented.
