Experimental observation of two-dimensional focusing of x rays in backscattering
Kushnir V. I. , Suvorov E. V.
A focusing of CoKax χ radiation has been achieved with a spherically curved Ge (620) single crystal reflecting in a backscattering mode (20 ~ π). A point focus ~ 10//m in size has been obtained. The theoretical diffraction limit of the width of о _ the focus in this arrangement is 120 A. The luminosity is high.
