TL;DR: In this paper, a 0.51 kg CdWO 4 scintillating bolometer was used for future Double Beta Decay Experiments, where the simultaneous readout of the heat and the scintillation light allows to discriminate between different interacting particles aiming at the disentanglement and the reduction of background contribution, key issue for next generation experiments.

TL;DR: In this paper, a new type of scintillator especially suitable for pulse-radiation detection was reported, which is characterized by a multiple quantum well structure, and their radiation-induced emission spectra were obtained.
Abstract: We report a new type of scintillator especially suitable for pulse-radiation detection Thin films of organic/inorganic perovskite compound (n-C6H13NH3)2PbI4, which is characterized by a multiple quantum well structure, were bombarded by 20 MeV protons, and their radiation-induced emission spectra were obtained A single and sharp emission peak due to an exciton was observed at the wavelength of 524 nm This emission was clearly detected even at room temperature, and its quantum efficiency was very high The line shape of this emission did not change, retaining its sharpness, and no other emissions appeared throughout the irradiation The optical response of (n-C6H13NH3)2PbI4 is very fast (n-C6H13NH3)2PbI4 is a promising scintillator material, meeting requirements not satisfied by conventional scintillators

TL;DR: An experiment over a 5.5-km horizontal propagation path to explore the efficacy of conventional adaptive optics in strong-scintillation conditions showed a significant degradation in correction as the scintillation increased.
Abstract: Most atmospheric-turbulence-compensation experiments have been performed under weak-scintillation conditions; conventional phase-conjugate adaptive-optics systems usually provide good correction for these conditions. We have performed an experiment over a 5.5-km horizontal propagation path to explore the efficacy of conventional adaptive optics in strong-scintillation conditions. The experimental results showed a significant degradation in correction as the scintillation increased. The presence of branch points in the phase appears to be the primary reason for the degradation in correction as the scintillation increases.

TL;DR: In this article, the performance of a ZnSe crystal operated within the LUCIFER R&D experiment is reported, where the authors measured the scintillation yield, the energy resolution and the background in the energy region where the signal from 0νDBD decay of 82Se is expected with an exposure of 9.4 kgdays.
Abstract: Scintillating bolometers of ZnSe are the baseline choice of the LUCIFER experiment, whose aim is to observe the neutrinoless double beta decay of 82Se. The independent read-out of the heat and scintillation signals allows to identify and reject α particle interactions, the dominant background source for bolometric detectors. In this paper we report the performances of a ZnSe crystal operated within the LUCIFER R&D. We measured the scintillation yield, the energy resolution and the background in the energy region where the signal from 0νDBD decay of 82Se is expected with an exposure of 9.4 kgdays. With a newly developed analysis algorithm we improved the rejection of α events, and we estimated the increase in energy resolution obtained by the combination of the heat and light signals. For the first time we measured the light emitted by nuclear recoils, and found it to be compatible with zero. We conclude that the discrimination of nuclear recoils from β/γ interactions in the WIMPs energy region is possible, but low-noise light detectors are needed.
