Abstract

There has been much investigation of the photoemission process for excitation in the thermal, visible and ultra-violet ranges. However, little data is available for energies of diagnostic x-ray interest (30 to 150 kev). Of particular interest in the design of image systems is the energy distribution of the emitted photo-electrons. In order to understand this problem a model of the x-ray photoemission process was proposed and then verified with ionization chamber measurements. Model parameters were then applied to predict the performance of several image system configurations.
