Gas 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 کاملThe gas proportional scintillation counter / microstrip gas chamber hybrid detector
The gas proportional scintillation counter/microstrip gas chamber (GPSC/MSGC) hybrid detector for X-ray spectrometry is described. The detector uses a CsI-coated microstrip plate placed in direct contact with the gas-filling as the photosensor readout for the GPSC scintillation substituting for the photomultiplier tube (PMT). Usable photosensor maximum gain is limited by optical positive feedba...
متن کاملXenon–Neon Gas Proportional-Scintillation Counters for X-Rays Below 2 keV: A Monte Carlo Simulation Study
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, exhibit distortions that are related to losses of electrons and fluorescence photons to the radiation window. In this paper, a Monte Carlo simulation method that takes into account these losses investigates the use of Xe–Ne mixt...
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...
متن کاملSCINTILLATION 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...
