Abstract
The design features of the crystal-monochromator module, whose rocking-curve FWHM changes in a predetermined manner under the action of a thermal effect produced by a semiconductor infrared laser on its working surface, are described. The calculated and experimental data on the interactive control of the parameters of the described module’s rocking curve are presented. The possibility of using this module in X-ray topography for obtaining additional information on the actual surface structure of defective crystals is shown.
