SCINTILLATION PROPORTIONAL Xe COUNTER WITH WLS FIBER READOUT FOR LOW-ENERGY X-RAYS
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 well uniformity is possible. The counter could be used for ”dark matter” search and neutrino magnetic moment measurement and for detection of small am...
متن کاملDevelopment of High Pressure Xe Scintillation Proportional Counter for Experiments in ”low-background” Physics
Characteristics of a scintillation proportional counter with WLS fiber optics readout is described. The possibility of detection of the proportional scintillation signal produced by the single electron of primary ionization is shown. The counter can be applied for the experiments in ”low–background” physics which require a low energy threshold. E-mail : akimov [email protected]
متن کاملGas Scintillation Proportional Counters for High-Energy X-ray Astronomy
A focal plane array of high-pressure gas scintillation proportional counters (GSPC) for a balloon-borne hard-x-ray telescope is under development at the Marshall Space Flight Center. These detectors each have an active area of ~ 20 cm, and are filled with a high pressure (10 Pa) xenon-helium mixture. Imaging is via crossed-grid position-sensitive phototubes sensitive in the UV region. The perfo...
متن کاملScintillation detectors for x-rays
Recent research in the field of phosphor and scintillator materials and related detectors is reviewed. After a historical introduction the fundamental issues are explained regarding the interaction of x-ray radiation with a solid state. Crucial parameters and characteristics important for the performance of these materials in applications, including the employed measurement methods, are describ...
متن کاملThe Energy Resolution of Xenon-Neon filled Gas Proportional-Scintillation Counters for X-Rays Below 2 keV
The energy spectra of x-rays with energies below 2 keV measured at atmospheric pressure with standard Xe gas detectors, such as gas proportional-scintillation counters (GPSC), exhibit distortions that are related to losses of electrons and fluorescence photons to the radiation window. In this work, a Monte Carlo simulation method that takes into account these losses investigates the use of Xe-N...
