Two-phase emission detectors in search for rare events with low energy depositions
Abstract
This paper reviews applications of two-phase emission detectors using xenon as working media. This kind of detectors invented at MEPhI is extremely sensitive to ionization (down to single electrons) and can be very massive (in ton scale) in order to provide high count rate for quite rare events and organize an active shielding from natural radioactivity in the wallles configuration of readout system. The emission detectors found their unique application in the most sensitive at the moment experiments searching for cold dark matter in the form of weakly interacting massive particles (WIMPs). The RED-100 detector recently constructed at NRNU MEPhI can be used for the first observation of the elastic coherent neutrino scattering off xenon nuclei when the detector is installed practically on the Earth’s surface.
