RAPID X-RAY DIFFRACTION TOPOGRAPHY USING A HIGH-GAIN IMAGE INTENSIFIER

Abstract
Instantaneous display of diffracted beams and their rapid photographic recording are achieved through use of a 4‐stage light image intensifier (EMI 9694). Beams carrying only 10 x‐ray photons sec−1 mm−2 are clearly seen on intensifier output phosphor by the naked eye. With an x‐ray tube of 800‐W power only and total experiment time less than a minute x‐ray projection topographs revealing individual crystal lattice dislocations are obtained by photographing a television display of intensifier output phosphor.
