Abstract

An imaging x-ray microscope using an incoherent laser plasma source and zone plates is reported. The He-like line of 4.03 nm (1 X 10¹⁴ photons/sr/pulse) from a carbon plasma produced by a compact glass laser is used as a source. The x-ray source is monochromatized by a condenser zone plate and a pinhole. As an x-ray image detector, a Kodak 101-07 film and an MCP or a cooled backside illuminated CCD are used. An image of the #1000 copper mesh is obtained by a single x-ray pulse at a magnification of 10 by the CCD. In the case of a singe pulse, the magnification is limited so that enough photons are incident on a pixel of the CCD. Thus, the spatial resolution is limited. Further improvement such as an ellipsoidal mirror with multilayer coating is considered to improve the resolution.
