Abstract

During the past few years an x-ray microscope and a scanning x-ray microscope have been developed at the University of Gottingen using condenser zone plates and high resolution microzone plates as x-ray lenses. The experimental equipment installed at the BESSY storage ring in Berlin is described. X-ray microscopic experiments with biological specimens with a resolution of ~50 nm are described. Viability tests of spores of Dawsonia superba are discussed and estimations of lethal doses at 270- and 500-eV radiation are given. Future developments are briefly reviewed: optics for higher resolution and with higher efficiency and the development of a laboratory x-ray microscope with a plasma x-ray source.
