    摘要: Photocontrolled ion-flow electron radiography apparatus has a multi-layered mesh structure, comprised of a conductive apertured sheet supporting an insulating layer, overlayed with a conductive screen and a top-most layer of photoconductive material, to control an ion stream responsive to a charge image formed in the photoconductive layer responsive to a pattern of x-rays differentially-absorbed by an object to be analyzed.
