Laboratory source based full-field x-ray microscopy at 9 keV
In the past decade, hard x-ray transmission microscopy experienced tremendous developments. With the availability of efficient Fresnel zone plates, even set-ups utilizing laboratory sources were developed . In order to improve the performance of these x-ray microscopes, novel approaches to fabricate optical elements  and brighter x-ray tubes  are promising candidates. We are currently building a laboratory transmission x-ray microscope for 9.25 keV, using an electron impact liquid-metal-jet anode source. Up to now, the further elements of our setup are: a polycapillary condenser, a tungsten zone plate, and a scintillator which is optically coupled to a CMOS camera. However, further variations in terms of optical elements are intended. Here we present the current status of our work, as well as first experimental results.
