Tabletop Bremsstrahlung X-ray holography: Making multiwavelength X-ray holograms

We have used a tabletop x-ray holography apparatus to measure the bremsstra hlung x-ray intensity distribution produced by electron bombardment of a si ngle crystal Ag anode over a far-field hemisphere to parts in 10(4). Using simple computer analysis, we have holographically reconstructed the image o f the atoms without the need for detailed crystallographic modeling. We hav e successfully imaged the silver atoms using both 27.6 and 19.6 keV bremsst rahlung photons.
