“…A further improvement was achieved moving from a bi-layer to a tri-layer of aluminum-titanium-aluminum, in order to enhance the acoustic match between KID and silicon. The best performance was obtained with a three-layer (14 nm Al, 33 nm Ti, 30 nm Al) that, thanks to a 8 times higher kinetic inductance than aluminum, allowed a very competitive baseline energy resolution of 26 eV RMS [50].…”

The next generation of bolometric experiments searching for rave events, in particular for the neutrino-less double beta decay, needs fast, high-sensitivity and easy-to-scale cryogenic light detectors. The CALDER project (2014–2020) developed a new technology for light detection at cryogenic temperature. In this paper we describe the achievements and the final prototype of this project, consisting of a $$5\times 5~\hbox {cm}^2$$ 5 × 5 cm 2 , $$650~\upmu \text {m}$$ 650 μ m thick silicon substrate coupled to a single kinetic inductance detector made of a three-layer aluminum-titanium-aluminum. The baseline energy resolution is $$34\pm 1$$ 34 ± 1 (stat)$$\pm 2$$ ± 2 (syst) eV RMS and the response time is $$120~\upmu $$ 120 μ s. These features, along with the natural multiplexing capability of kinetic inductance detectors, meet the requirements of future large-scale experiments.

“…In the last years several R&D activities were performed, both using TeO 2 as in CUORE, and other crystals featuring a larger light emission (some of the most recent results can be found in Refs. [54][55][56][57][58][59][60][61] and references therein). These efforts gave birth to two medium scale projects: Lumineu (Modane, France [62]) and CUPID-0 (LNGS, Italy [63][64][65][66]) to study the 0νDBD decay of 100 Mo and 82 Se respectively.…”

Neutrinoless Double Beta Decay is a hypothesised nuclear process in which two neutrons simultaneously decay into protons with no neutrino emission. The prized observation of this decay would point to the existence of a process that violates a fundamental symmetry of the Standard Model of Particle Physics, and would allow to establish the nature of neutrinos. Today, the lower limits on the half-life of this process exceed 10^{25}25-10^{26}26 yr. I will review the current status of the searches for Double Beta Decay and the perspectives to enhance the experimental sensitivity in the next years.

“…The detector reached a baseline energy resolution of about 80 eV RMS, constant in a temperature range from 10 mK up to 200 mK [23]. Because of its robust performance we chose this prototype, even if CALDER proved that more sensitive superconductors provided an even better energy resolution [24].…”

Molybdenum based crystals such as Li 2 MoO 4 and CaMoO 4 are emerging as leading candidates for next generation experiments searching for neutrino-less double beta decay with cryogenic calorimeters (CUPID, AMoRE). The exquisite energy resolution and high radio-purity of these crystals come at the cost of a potentially detrimental background source: the two neutrinos double beta decay of 100 Mo. Indeed, the fast half-life of this decay mode, combined with the slow response of cryogenic calorimeters, would result in pileup events in the energy region of interest for neutrinoless double beta decay, reducing the experimental sensitivity. This background can be suppressed using fast and high sensitivity cryogenic light detectors, provided that the scintillation time constant itself does not limit the time resolution. We developed a new detection technique exploiting the high sensitivity, the fast time response and the multiplexing capability of Kinetic Inductance Detectors. We applied the proposed technique to a 2 × 2 × 2 cm 3 Li 2 MoO 4 crystal, which was chosen as baseline option for CUPID. We measured simultaneously both the phonon and scintillation signals with KIDs. We derived the scintillation time constant of this compound at millikelvin temperatures obtaining τ scint = 84.5 ± 4.5(syst) ± 1.0(stat) μs, constant between 10 and 190 mK.
