Abstract :
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. We show that we can obtain a spectral resolution of 9.1% FWHM at 5.9 keV over a useful area of 100 cm2. We demonstrate that signal rise-time discrimination can be used to reject non-X-ray background as efficiently as in ordinary proportional counters.
