“…d) Convert to detected photon energy by multiplying by the mean energy E of the emitted photons for each crystal (NaI: 3.3 eV [28], NaI(Tl): 2.95 eV [28], CsI: 3.9 eV [35]). More recent work on NaI(Tl) [40] identifies two peaks at 2.82 eV and 3.76 eV at 4 K; however, in our case, the actual photon energy does not have much effect on the width of the band which is dominated by phonon channel resolution (see g) below). e) Account for the light detector resolution σ L by applying a random fluctuation from a normal distribution with standard deviation σ = σ L to the detected light energy E L .…”

Scintillating calorimeters are cryogenic detectors combining a measurement of scintillation with one of phonons to provide particle identification. In view of developing alkali halide devices of this type able to check the DAMA/LIBRA claim for the observation of dark matter, we have simulated detector performances to determine their sensitivity by two methods with little model-dependence. We conclude that if performance of the phonon channel can be brought in line with those of other materials, an exposure of 10 kg-days would suffice to check the DAMA/LIBRA claim in standard astrophysical scenarios. Additionally, a fairly modest array of 5 kg with background rejection would be able to directly check the DAMA/LIBRA modulation result in 2 years.

Inorganic crystal scintillators play a crucial role in particle detection for various applications in fundamental physics and applied science. The use of such materials as scintillating bolometers, which operate at temperatures as low as 10 mK and detect both heat (phonon) and scintillation signals, significantly extends detectors performance compared to the conventional scintillation counters. In particular, such low-temperature devices offer a high energy resolution in a wide energy interval thanks to a phonon signal detection, while a simultaneous registration of scintillation emitted provides an efficient particle identification tool. This feature is of great importance for a background identification and rejection. Combined with a large variety of elements of interest, which can be embedded in crystal scintillators, scintillating bolometers represent powerful particle detectors for rare-event searches (e.g., rare alpha and beta decays, double-beta decay, dark matter particles, neutrino detection). Here, we review the features and results of low-temperature scintillation detection achieved over a 30-year history of developments of scintillating bolometers and their use in rare-event search experiments.

A superconducting quantum interference device (SQUID) is a very sensitive magnetometer used to measure extremely subtle magnetic fields based on superconducting loops containing Josephson junctions. SQUID represents the most accurate sensor to measure the magnetic field and voltage. Overview of the potential applications and possible improvements of SQUID are the aims of this work. In general, the transducers of physical quantities on voltage and magnetic field allow wide range of other applications. Such converters may lead to an improved universality of SQUID´s. Potential improvements was verified by simulation of series and parallel multiple quantum interference devices. It provides opportunities to improve their sensitivity.
