Image quality with Kirkpatrick-Baez microscope in hard X-ray

An important diagnosis method——Kirkpatrick-Baez microscope system in ICF experiments was researched. The brief aberration of the Kirkpatrick-Baez microscope was calculated. The main aberration, spherical aberration was analyzed, and the spherical aberration is 94% of the total aberration. The configuration was simulated by the ray tracing method. Resolutions in different fields and mirror-lengths were compared. The modal of Kirkpatrick-Baez microscope was made in computer with 10 μm resolutionat 8 keV. It was studied about the adjusting tolerance method of Kirkpatrick-Baez microscope. When numerical aperture is 0.003 7, the angle error range is -0.087°~0.067°。
