| アブストラクト: |
Ｘ-ray wave guides are optical elements for hard x-rays capable to produce x-ray beams below 100 nm with a gain (in one dimension) of the order of 100. The basic principle is a resonance effect which takes place in a three-layer structure under grazing incidence conditions. The outgoing beam is coherent and allows phase contrast microscopy and micro-diffraction with high spatial resolution. In the seminar the basic principle will be illustrated together with few applications. In particular will be presented strain measurements with high spatial resolution in materials for microelectronics and structural characterization of biomaterials. |
