Description

Bolometric light detectors provide an efficient method to collect light signals at small thresholds in cryogenic experiments and are being exploited in next-generation experiences for the search of Neutrinoless Double Beta Decay. Sample light detecting bolometers made up of a ultra-pure Ge slab read by a phonon sensor thermistor were assembled and tested at very low temperatures, below 30 mK; their performances are investigated in terms of their reproducibility, signal amplitude, signal to noise ratio and energy resolution.
