The number of electrons initially created by the absorption of a soft X-ray photon in a parallel plate proportional counter may be counted by detection of the fast light pulses emitted from the resulting electron avalanches. The authors show that good energy resolution may be achieved (about 34% at C-K, 0.28 keV) with this technique. Using the light signal it is also possible to image events by means of an image intensifier, and position resolution of 350 ..mu..m FWHM at 0.28 keV has been achieved without event centroiding.
