Abstract
During the last years an X-ray microscope has been developed at the University of Göttingen based on the development of condenser zone plates and high resolution micro zone plates as X-ray lenses. The X-ray optical and mechanical set up of the system, which has been established at the BESSY storage ring in Berlin, is described in /1/. X-ray microscopy experiments of biological specimens with a resolution of 50 nm and exposure times of a few seconds have been performed using this microscope with synchrotron radiation of the storage ring in the wavelength region between 2.3 nm and 4.5 nm. As an example spores of the moss Dawsonia superba have been imaged /2/. In addition, measurements have been made to determine the lethal radiation dose for these spores.
