摘要

A four-channel multilayer Kirkpatrick-Baez (KB) microscope is developed for the 8-keV X-ray imaging of experiments on laser inertial confinement fusion (ICF).A periodic multilayer that works at 8 keV and with a grazing incidence angle of 1.0° is coated on reflective surfaces to achieve a spatial resolution higher than 5 μm and an effective solid angle higher than ～10-7 sr.A precise assembly is realized by a conical reference cone to couple with an X-ray framing camera.This study provides detailed information on an optical and multilayer design,assembly method,and experimental results with a Cu X-ray tube.The instrument provides a high-resolution and high-throughput X-ray image for backlit or self-emission imaging of laser plasma at Cu Kα line radiation in Shenguang series laser facilities.
