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 کاملA new method for pulse analysis of driftless-gas proportional scintillation counters
A new method for pulse analysis of driftless-gas proportional scintillation counters (GPSCs) is presented. With this method the requirement for additional analog or digital signal time-analysis and pulse-amplitude correction currently used is eliminated. In contrast to conventionaland driftless-GPSCs that have always relied on long shaping-time constants (several ms), the use of very short line...
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 کاملLow-background Experiments with High Pressure Gas Scintillation Proportional Detector
A scintillation proportional counter with wavelength shifting fiber readout filled with Xe or Kr under a pressure of up to 20 atm is proposed for the low–background experiments on search for dark matter of the Universe and 2K–decay of Kr.
متن کاملA Time Compensator for Large Scintillation Counters*
A circuit is described which develops time-invariant pulses for large scintillation trigger counters. For a 8.56 ft long counter, a unit capable of f 22 nsec range is described; the constancy of delay of output for this unit over the full delay range is typically & 400 psec. * Work supported by the U. S. Atomic Energy Commission. (Submitted to Nucl. Instr . & Methods. ) 1 D Introduction One of ...
