Notes:
A microscopic model for low energy electron interaction in alkali halides was used to simulate secondary electron emission from CsI induced by x rays with energies up to 100 keV. The integral "current'' and "pulse'' yields were calculated as function of the x-ray energy, CsI convertor thickness, and angle of incidence. We observe a decrease in true low energy (〈50 eV) secondary electron yields at increasing x-ray energies and discuss the effectiveness of CsI convertors coupled to gaseous electron multipliers developed for fast, high resolution x-ray imaging.
