The possibilities of using x-ray capilary optics in lithography and microscopy are discussed. It has been shown experimentally that these systems, originally proposed by M. A. Kumakhov, may considerably simplify experimental designs. A micropinch x-r

Soft X-ray laser have recently shown a dramatic reduction in the pump energy needs. Grazing incidence pumping geometry constitutes the last achieved milestone on the way to real repetitive soft X-ray lasers. We present the results of the experimental

By the use of a thin highly oriented pyrolytic graphite crystal (HOPG) bent to a high-performance ellipsoidal shape it was possible to focus monochromatic x-rays of 4.5 keV photon energy with an efficiency of 0.0033, which is 30 times larger than for

Practically achieved parameters of capillary optics are presented. A micro x-ray fluorescence (XRF) arrangement was realized by using a microfocus x-ray tube and a capillary optic. Several examples for application of micro XRF are given. It was shown

Energy dispersive microdiffractometry can be carried out using a microfocus x-ray source coupled to a polycapillary lens, which provides an 8000-fold intensity gain. As result this letter shows the orientation of molybdenum microcrystallites over a s
