First test of a Li2WO4(Mo) bolometric detector for the measurement of coherent neutrino-nucleus scattering

Assessment of Cs2HfCl6 crystal applicability as low-temperature scintillating bolometers by their thermodynamic characteristics

“…10. The time constants of the ZWO and LD bolometric signals (respectively increase and decay time parameters) were measured to be in B1-10 ms range, and are in agreement with what is usually observed for the NTD Ge thermistor technology (e.g., see 24,25,[54][55][56][57] and references therein).…”

Scintillation in Low-Temperature Particle Detectors

“…The Li ( 6 Li) content ensures the neutron detection capability, as demonstrated with other Li-containing scintillating bolometers, while the presence of a heavy target (W) increases the CENNS events detection rate [55]. Therefore, a low-threshold LiWO 4 (Mo) scintillating bolometer is particularly interesting to be used as CENNS detector, neutron flux monitor, and/or active veto [422].…”

“…A first scintillating bolometric test of the material was done with a Cz-grown Li 2 Mo 0.08 W 0.92 O 4 crystal ( 18 × 7 mm, 8 g) coupled to a 44 mm Ge LD [422]. A rather low scintillation signal (L/H γ(β) = 0.17 keV/MeV) was detected, but the result is affected by non-optimal light collection (the absence of a reflective film around the lateral side of the crystal and uncoated Ge wafer).…”

The low temperature heat capacity of Li2Mo0.05W0.95O4

“…They possess luminescent and scintillation properties [1][2][3][4]. Such properties allow their use as optical elements of various equipment, including as cryogenic phonon-scintillation detectors for the search of neutrinoless double beta decay [5][6][7]. Numerous studies of Li2MoO4, including its structural, optical, scintillation, and thermodynamic characteristics, are presented in the literature.…”

“…Until recently, it was assumed that Li2WO4 could not be grown by the Czochralski method due to the presence of a high-temperature phase transition. Therefore, a series of works on growing Li2WO4 doped with molybdenum [5,8,9], which showed the possibility of obtaining crystals with molybdenum content from 15 to 2.5%. Currently, the low-temperature heat capacity of lithium molybdate has been studied [10].…”
