Description

FLARES is an innovative project in the field of rare events searches, such as the search for the neutrinoless double beta decay. It aims to demonstrate the high potentiality of a technique that combines ultra-pure scintillating crystals to arrays of high performance silicon drift detectors (SDD), used to read their light. By optically coupling the two devices and working at temperatures of about 120K, a strong enhancement of the light emission should be obtained. This would allow to reach a 1% level energy resolution in a scintillation particle detector. The proposed technique will therefore combine in a single device all the demanding features needed by an ideal experiment looking for rare events. It should in fact guarantee high energy resolution, background abatement (provided specific features of the scintillating crystals that allow a strong abatement of the background due to alpha particles), low cost mass scalability and high flexibility in choice of the crystal. The performances of a first production of matrices of SDD as well as first measurements of the low temperature light yield of a selection of high purity scintillating crystals will be presented and discussed.
