Abstract: The number of electrons emitted from a metal surface that is being bombarded by x-rays is increased by utilizing a secondary electron emission process within an insulator, potassium chloride (KCl), that is deposited on a metal, gold (Au) layer. The problem of obtaining a maximum electron yield from these layers is one of optimizing the secondary electron emission in the KCl for a given x-ray energy. This optimization is a function of the thickness of the KCl, its density, temperature, and an internal electric field.
