Experimental observation of dynamic focusing of x rays by a uniformly bent crystal in the Laue case
Kushnir V. I., Suvorov E. V.
The earlier predicted dynamic focusing of χ rays by a uniformly bent crystal with a magnification different from unity has been observed experimentally. A diffracted beam can be compressed to a width of ^ 8 μηι, which is an order of magnitude smaller than the base of a Borrmann triangle.
