“…of up to ∼2 µs, at the level of ∼1% of the initial amplitude of the scintillation signal, could also be observed in the study reported in [94]. This component disappeared completely when an electric field of a few kV/cm was applied, which confirms its recombination origin.…”

We review the current status of liquid noble gas radiation detectors with energy threshold in the keV range, which are of interest for direct dark matter searches, measurement of coherent neutrino scattering and other low energy particle physics experiments. Emphasis is given to the operation principles and the most important instrumentation aspects of these detectors, principally of those operated in the double-phase mode. Recent technological advances and relevant developments in photon detection and charge readout are discussed in the context of their applicability to those experiments.

“…The signal would be further reduced due to the fact that the electron emission probability from liquid Kr is about 60% at 3 kV/cm [10,12]. In addition, the electron-ion recombination in the liquid may also reduce the signal, by a factor of 1.1-1.2 [12,31]. Combined effect of these factors results in that the electron collection efficiency in the cathode gap in the two-phase mode is by a factor of 20 and 10 lower than that in the gaseous mode, for X-rays and β-particles respectively.…”

We study the performances of gaseous and two-phase (liquid-gas) cryogenic detectors of ionizing radiation based on gas electron multipliers (GEMs) and operated in an avalanche mode in pure noble gases. The gas amplification in He, Ar and Kr is systematically studied at low temperatures, using triple-GEM multipliers. High gains, exceeding 10 4 , were obtained in these gases in the range of 120-300 K. Stable electron avalanching was demonstrated in a saturated Kr vapor in the two-phase mode. These results are relevant for understanding basic mechanisms of electron avalanching at low temperatures and for applications in cryogenic particle detectors, in particular in dark matter and solar neutrino detectors.

“…The VUV luminescence is produced by the decay of singlet and triplet states of the Xe * 2 excimer. These can be formed directly by excited atoms left by the interacting particle or as a result of recombination into an excited state along the particle track [13,17]. Figure 3 shows MCA spectra taken from one PMT.…”

ZEPLIN-III is a direct dark-matter search instrument using liquid xenon as a target. Both the scintillation light and the ionisation charge are measured. The instrument has been built and it is currently being testing in a surface laboratory. We present results from some of the initial testing, including design thermal control system verification, photomultiplier calibration (including spectral measurements with 60 keV photons from 241 Am) and two-phase operation showing simultaneous measurement of scintillation and charge and position reconstruction.
