“…Thanks to highly-efficient α/β separation achieved by the Li 2 MoO 4 scintillating bolometers, we selected the α events to investigate the radioactive contamination of the crystals to be exhibited by α-active radionuclides from U/Th families. The performed analysis is similar to one described in details in [14]. As it is seen in Fig.…”

A new R&D on lithium molybdate scintillators has begun within a project CLYMENE (Czochralski growth of Li 2 MoO 4 crYstals for the scintillating boloMeters used in the rare EveNts sEarches). One of the main goals of the CLYMENE is a realization of a Li 2 MoO 4 crystal growth line to be complementary to the one recently developed by LUMINEU in view of a mass production capacity for CUPID, a next-generation tonne-scale bolometric experiment to search for neutrinoless double-beta decay. In the present paper we report the investigation of performance and radiopurity of 158-g and 13.5-g scintillating bolometers based on a first large-mass (230 g) Li 2 MoO 4 crystal scintillator developed within the CLYMENE project. In particular, a good energy resolution (2-7 keV FWHM in the energy range of 0.2-5 MeV), one of the highest light yield (0.97 keV/MeV) amongst Li 2 MoO 4 scintillating bolometers, an efficient alpha particles discrimination (10σ) and potentially * Corresponding author low internal radioactive contamination (below 0.2-0.3 mBq/kg of U/Th, but 1.4 mBq/kg of 210 Po) demonstrate prospects of the CLYMENE in the development of high quality and radiopure Li 2 MoO 4 scintillators for CUPID.

“…Indeed, choosing 0νDBD candidates with high Q-value, such as 82 Se or 100 Mo, provides a natural reduction of the background contribution from environmental γ's, that drops above the 2.6 MeV γ-line of 208 Tl. An extensive R&D activity allowed to characterize the properties of several compounds grown with such emitters, like ZnSe [21,22], ZnMoO 4 [23,24,25,26,27,28,29] or Li 2 MoO 4 [30,31,32,33,34]. These R&Ds demonstrated that the simultaneous read-out of light and heat in scintillating calorimeters enables a very effective suppression of the α background.…”

The suppression of spurious events in the region of interest for neutrinoless double beta decay will play a major role in next generation experiments. The background of detectors based on the technology of cryogenic calorimeters is expected to be dominated by particles, that could be disentangled from double beta decay signals by exploiting the difference in the emission of the scintillation light. CUPID-0, an array of enriched ZnSe scintillating calorimeters, is the first large mass demonstrator of this technology. The detector started data-taking in 2017 at the Laboratori Nazionali del Gran Sasso with the aim of proving that dual read-out of light and heat allows for an efficient suppression of the background. In this paper we describe the software tools we developed for the analysis of scintillating calorimeters and we demonstrate that this technology allows to reach an unprecedented background for cryogenic calorimeters.

“…Phonon-mediated cryogenic detectors using massive absorbers are a mature technology extensively employed in rare event physics experiments, like neutrinoless double beta decay (0νDBD) searches [1] (see for example CUORE [2], CUPID-0 [3], LUMINEU [4], AMoRE [5]...) and dark matter direct detection experiments [6,7] (EDELWEISS [8] , Super-CDMS [9], CRESST [10]...). Generally the working temperature is <100 mK and the most common phonon sensors are Neutron Transmutation Doped (NTD) Ge thermistors, which are glued to the detector surface and depending on the gluing characteristics are more or less sensitive to the ballistic component, or Transition Edge Sensors (TES), which usually are sensitive to the ballistic phonons.…”

Measurements and Simulations of Athermal Phonon Transmission from Silicon Absorbers to Aluminum Sensors

et al. 2019

Phonon reflection/transmission at the interfaces plays a fundamental role in cryogenic particle detectors, in which the optimization of the phonon signal at the sensor (in case of phonon-mediated detectors) or the minimization of the heat transmission (when the detection occurs in the sensor itself) is of primary importance to improve sensitivity. Nevertheless the mechanisms governing the phonon physics at the interfaces are still not completely understood. The two more successful models, Acoustic Mismatch Model (AMM) and Diffuse Mismatch Model (DMM) are not able to explain all the accumulated experimental data, and the measurement of the transmission coefficients between the materials remains a challenge. Here, we use measurements of the athermal phonon flux in aluminium Kinetic Inductance Detectors (KID) deposited on silicon substrates following a particle interaction to validate a Monte Carlo (MC) phonon simulation. We apply the Mattis-Bardeen theory to derive the phonon pulse energy and timing from the KID signal and compare the results with the MC for both AMM and DMM models, finding a remarkable good agreement for AMM. For an aluminum film of 60 nm and a silicon substrate of 380 µm, we obtain transmission coefficients Si-Al in the range [0.3 -0.55] and Si-Teflon in the range [0.1 -0.15].
