SCINTILLATION PROPORTIONAL XE COUNTER WITH WLS FIBER READOUT FOR LOW-ENERGY X-RAYS

Abstract A gas Xe-based scintillation proportional counter with cylindrical geometry and wavelength shifting (WLS) fiber readout for X-rays of energy 0.5–100 keV is proposed. With such a design large sizes and sensitive area of the counter with a fairly good uniformity is possible. The counter could be used for “dark matter” search and neutrino magnetic moment measurement and for detection of small amounts or traces of radioactive elements in substances or environment.
