Abstract Fusion energy research has in the past 40 years focused primarily on tokamak concept, but recent advances plasma theory and computational power have led to renewed interest stellarators. The largest most sophisticated stellarator world, Wendelstein 7-X (W7-X), just started operation, with aim show that earlier weaknesses of this concept been addressed successfully, intrinsic advantages persist, also at parameters approaching those a future fusion plant. Here we first physics...

The CUPID-Mo experiment at the Laboratoire Souterrain de Modane (France) is a demonstrator for CUPID, next-generation ton-scale bolometric $0\ensuremath{\nu}\ensuremath{\beta}\ensuremath{\beta}$ experiment. It consists of 4.2 kg array 20 enriched ${\mathrm{Li}}_{2}$$^{100}\mathrm{Mo}{\mathrm{O}}_{4}$ scintillating bolometers to search lepton-number-violating process decay in $^{100}\mathrm{Mo}$. With more than one year operation ($^{100}\mathrm{Mo}$ exposure $1.17\text{ }\text{...

Results are reported of an experimental search for the unique, rapidly varying temporal pattern solar axions coherently converting into photons via Primakoff effect in a single crystal germanium detector when incident at Bragg angle with crystalline plane. The analysis 1.94 kg yr data from 1 DEMOS Sierra Grande, Argentina, yields new laboratory bound by axion-photon coupling...
A bstract Neutrinoless double-beta decay is a key process in particle physics. Its experimental investigation the only viable method that can establish Majorana nature of neutrinos, providing at same time sensitive inclusive test lepton number violation. CROSS (Cryogenic Rare-event Observatory with Surface Sensitivity) aims developing and testing new bolometric technology to be applied future large-scale experiments searching for neutrinoless promising nuclei 100 Mo 130 Te. The limiting...
A scintillating bolometer based on a large cubic Li$_{2}$$^{100}$MoO$_4$ crystal (45 mm side) and Ge wafer (scintillation detector) has been operated in the CROSS cryogenic facility at Canfranc underground laboratory Spain. The dual-readout detector is prototype of technology that will be used next-generation $0\nu2\beta$ experiment CUPID. measurements were performed 18 12 mK temperature pulse tube dilution refrigerator. This setup utilizes same as CUORE cryostat host CUPID so represents an...
Phonon-mediated particle detectors based on single crystals and operated at millikelvin temperatures are used in rare-event experiments for neutrino physics dark-matter searches. In general, these devices not sensitive to the impact point, especially if detection is mediated by thermal phonons. this Letter, we demonstrate that excellent discrimination between interior surface β α events can be achieved coating a crystal face with thin metallic film, either continuous or form of grid. The...
Two measurements of the half-life 2 nu beta -decay 76Ge are reported. One was made with PNL-USC natural isotopic abundance germanium twin detectors. T12/2 =(1.12+-0.26+0.48)*1021 y (2 sigma ), and one a Soviet-manufactured 0.25-kg Ge (Li) detector isotopically enriched to 85% in 76Ge, (9.2+-0.4+0.7)*1020 ). Both were measured same facility. These values good agreement nuclear structure calculations an independent measurement by ITEP-YPI collaboration.
Abstract CUPID-Mo is a cryogenic detector array designed to search for neutrinoless double-beta decay (0νββ) of 100 Mo. It uses 20 scintillating Mo-enriched Li 2 MoO 4 bolometers instrumented with Ge light detectors perform active suppression α backgrounds, drastically reducing the expected background in 0νββ signal region. As result, pileup events and small instabilities that mimic normal signals become non-negligible potential backgrounds. These types can principle be eliminated based on...
