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.
