Abstract

We describe the effect of X-ray absorption in the avalanche region of a parallel plate proportional counter. We calculate the magnitude of this effect for several different input spectra, using detectors having differing internal dimensions, gas compositions and pressures. The influence on the energy resolution of the EXOSAT and PGI parallel plate proportional counters is shown to be insignificant for most spectra.
