Periodic multilayer KB microscopes have widely implemented in x-ray diagnostic experiments of ICF, especially at relatively high x-ray energies (8keV or higher). But the obvious disadvantage, due to narrow bandwidth of periodic multilayer, is the ununiformity of x-ray image brightness and the limited field of view. The literature describes the characterization of a high-energy KB microscope with aperiodic multilayer configured to achieve larger effective field of view than existing periodic multilayer KB microscopes. The microscope, working on 8keV with grazing angles of 1.1330° and 1.1837°, is capable of 5μm resolution over ±200μm object field. Design of the multilayer and experimental results with a Cu x-ray tube will be shown.
