ABSTRACT:
A method of x-ray topography of crystals at cryogenic temperatures which s not require continuous pumping of the sample chamber during low-temperature operation. The method eliminates the problems of vibrations degrading the high-resolution photographic image recorded and also prevents loss of the sample's angular alignment with the x-ray beam caused by torques produced by a vacuum-coupling mechanism.
