Production of reflection point sources for hard X-ray gabor holography

The production of point X-ray sources for hard X-rays of approximately 8 keV is proposed and their application to Gabor holography is examined. Small X-ray sources less than, 100 nm in diameter are obtained by total reflection from a limited surface area at grazing incidence. A microstrip plated with heavy metal on a glass plate is used for a one-dimensional small X-ray source and crossed glass rods for a two-dimensional X-ray source. A virtual source width smaller than approximately 80 nm is demonstrated. Young's X-ray interference fringes are obtained using beams reflected from two microstrips. Gabor X-ray holograms of a gold wire and a diatom are recorded with a virtual point source and their reconstructed images are numerically obtained.
