A large-area gas scintillation proportional counter for X-ray astronomy
An improved large-area gas scintillation proportional counter has been built, suitable for use in X-ray astronomy. This counter employs electron focusing in a drift region to achieve uniform response. It is shown that a spectral resolution of 9.1% FWHM at 5.9 keV can be obtained over a useful area of 100 sq cm. It is demonstrated that signal rise-time discrimination can be used to reject non-X-ray background as efficiently as in ordinary proportional counters.

Recent developments in parallel-grid, gas-scintillation proportional counters
The problems of developing large-area, gas-scintillation proportional counters with high resolution are considered. It is found that simple large-area, parallel-grid proportional counters suffer from a variation in gain over the counter window. Some success has been achieved in overcoming this problem by focusing the charge cloud as it drifts into the multiplication region. Measurements are reported for various mixtures of argon and xenon as well as pure xenon.

A focusing gas scintillation proportional counter
An improved large-area gas scintillation proportional counter has been built, suitable for use in X-ray astronomy. This counter employs electron focusing in a drift region to achieve uniform response. It is shown that a window area of 60 sq cm and a spectral resolution of 10% fwhm or better at 5.9 keV can be obtained.
