Welcome to Cupid-0

Overview

CUPID-0 is the first demonstrator of the CUPID project, which aims to build a future-generation bolometric experiment to search for neutrinoless double beta decay (0νββ): this is a very rare, never observed process, that, if existing, can answer to some unsolved questions about neutrinos...

CUPID-0 Detector

CUPID-0 is the first 0νββ experiment using the scintillating bolometers technique. The detector is an array of 26 ZnSe crystals (24 highly enriched in 82Se at a level of 95% and 2 naturals) arranged in 5 tower-like structures. The crystals are interleaved with very thin Ge slabs operating as bolometric light detectors...

CUPID-0 Cryostat

The CUPID-0 cryostat was build in 1988 by OXFORD INSTRUMENTS. It is a completely custom wet cryostat, made with radiopure materials, able to reach a base temperature of about 7.5 mK. The setup hosted several double beta decay experiments in the past: MIBETA, Cuoricino, and CUORE-0...
