CUORE

CUORE (Cryogenic Underground Observatory for Rare Events) is a detector under construction at Laboratori Nazionali del Gran Sasso of INFN. The detector has been designed to observe the neutrinoless double beta decay and investigate the possible Majorana-like behaviour for the neutrino itself. The detector will be capable of detecting efficiently dark matter particles with a mass of the order of 10GeV.

CUORE is an array of 988 Tellurium Oxide crystals, 750g each, which will be kept at 10mK in a properly designed cryostat. The main issue for this experiment are the refrigeration (the most powerful dilution refrigerator of the world has been developed for CUORE) and the background suppression. The material specifications are outsdandingly tight: for example, the copper in close contact to the crystal must be delivered in the underground lab no later than three months after the casting to avoid cosmic rays activation.

I'm involved in the construction and characterisation of the mechanical suspension of the detector, which is connected to a proper support at room temperature on one side and to the detector support at 10mK on the other side. To guarantee the proper resolution for the crystals, which are operated as bolometers, the reduction of the vibration transmission is a crucial issue.
