Abstract :
A gas scintillation proportional counter has been constructed for use in detecting subkiloelectron-volt X-rays from cosmic sources. Over a sensitive area of 5 cm2, this instrument has a measured energy resolution of 85 eV (FWHM) at 149 eV. This is significantly better than similarly sized solid state detectors. Rise-time discrimination is used both to reject space background and to reduce low energy noise below 50 eV. The development of an imaging capability for this instrument is discussed.
