The first experimental attempts to detect 0νββ decay are date back to the 1940s. Over the decades, many different technologies have been developed to search for this process on a variety of candidate isotopes. Presently, CUORE²⁾ is one of the most sensitive experiments in the field. It is located at the Laboratori Nazionali del Gran Sasso (LNGS) of INFN, in the Abruzzo region in central Italy. CUORE is composed of 988 TeO₂ crystals operated as cryogenic calorimeters at a temperature of 10-15 mK. The crystals act simultaneously as detectors and source of 0νββ decay: in fact, they contain the ββ decay isotope ¹³⁰Te, that contributes to ~27% of the crystal mass. The CUORE detectors are operated in the largest dilution refrigerator ever build³⁾, capable of cooling down ~1.5 tons of material to base temperature about a month, and operating it stably for years.
