Image Intensifier System for Dynamic X-Ray Diffraction Studies

Abstract
A cascaded image intensifier has been incorporated in a system which permits study of dynamic changes in x‐ray diffraction patterns. An RCA C70021A three stage, magnetically focused, image tube is coupled by a f/0.87 Super‐Farron lens to a 15.2 cm diam fluorescent screen to permit direct viewing of transmission x‐ray diffraction patterns. The image on the output phosphor is of sufficient intensity to be viewed directly, to be recorded cinematographically, or to be displayed by vidicon pick‐up on a television monitor.
