Allowance for diffraction focusing of x rays in an elastically-bent crystal
Petrashen' P.V., Chukhovskii F.N.
We demonstrate the feasibility, in principle, of dynamic diffraction focusing of χ rays by an elastically bent crystal in an exceedingly narrow (~10~5) interval of angles with an intensity transfer function q(a),il>) 1 and with an image magnification coefficient K> 1.
