Measurement of single-electron noise in a liquid-xenon emission detector

Abstract

A technique for studying single-electron noise in emission detectors that are intended for detection of rare processes with small energy releases is developed. Examples of possible applications are experiments for search of dark matter in the Universe and detection of reactor antineutrinos via coherent neutrino scattering at heavy xenon nuclei. We present the first results of studying the nature of single-electron noise in a liquid-xenon emission detector and consider possible ways to suppress it.
