A large-area gas scintillation proportional counter for X-ray astronomy.
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. 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.
