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 elimina

The results of a comparative study of a xenon gas proportional scintillation counter instrumented with photosensors based on two variants of a CsI photocathode and a microstrip plate are reported. The photosensors were isolated from the gas proportio

We report the performance characteristics of a new microstructure, the Micro-Hole-and-Strip Plate (MHSP), operated initially as an X-ray proportional counter. The MHSP is a combination of the features of a microstrip plate (MSP) and a gas electron mu

The performance characteristics of a xenon gas proportional scintillation counter instrumented with an large-area avalanche photodiode with enhanced UV-sensitivity were evaluated. By integrating the photodiode within the xenon gas envelope of the sci

The application of recently developed VUV silicon photodiodes as a replacement for the standard photomultiplier tube (PMT) in a gas proportional scintillation counter (GPSC) is investigated. A photodiode positioned within the gas envelope would resul

The curved-grid technique was developed to maintain the superior performance of large-area gas proportional scintillation counters (GPSCs) without resorting to complex and bulky focusing systems or large photomultiplier tubes (PMTs) for applications

This work investigates the use of annihilation photons from gamma-ray-induced electron-positron pair production to inspect objects when only one side is accessible. The Z/sup 2/-dependence of the pair-production cross section and the high penetration

A xenon gas proportional scintillation counter has been instrumented with a novel photosensor that replaces the photomultiplier tube normally used to detect the VUV secondary scintillation light. In this implementation, the collection grid of a plana

We have observed that the pulse-height distributions of X-ray events that deposit essentially the same amount of energy in a xenon gas detector will vary according to the deexcitation pathways available to the photoionized atoms. A xenon gas proporti
