We have developed a microscope capable of imaging x-ray emission from inertial confinement fusion targets in the range of 7{endash}9 keV. Imaging is accomplished with a Kirkpatrick-Baez type, four-image microscope coated with a WB{sub 4}C multilayer having a 2d period of 140 {Angstrom}. This microscope design (a standard used on the University of Rochester{close_quote}s OMEGA laser system) is capable of 5 {mu}m resolution over a region large enough to image an imploded target ({approximately}400 {mu}m). This design is capable of being extended to {approximately}40 keV if state-of-the-art, short-spacing, multilayer coatings are used ({approximately}25 {Angstrom}), and has been configured to obtain 3 {mu}m resolution with the appropriate choice of mirror size. As such, this type of microscope could serve as a platform for multiframe, hard x-ray imaging on the National Ignition Facility. Characterization of the microscope and laboratory measurements of the energy response made with a cw x-ray source will be shown. {copyright} {ital 1999 American Institute of Physics.}
