IMAGE INTENSIFIER SYSTEM FOR DYNAMIC X-RAY DIFFRACTION STUDIES

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. © 1968 The American Institute of Physics.
