Abstract

This paper describes the setup of two different solutions for laboratory X-ray microscopy working with geometric magnification. One setup uses thin-film transmission targets with an optimized tungsten-layer thickness and the electron gun and optics of an electron probe micro analyzer to generate a very small X-ray source. The other setup is based on a scanning electron microscope and uses microstructured reflection targets. We also describe the structuring process for these targets. In both cases we show that resolutions of 100 nm can beachieved. Also the possibilities of computed tomography for 3D imagingare explored and we show first imaging examples of high-absorption aswell as low-absorption specimens to demonstrate the capabilities ofthe setups.
