4.75 keV four-channel Kirkpatrick-Baez microscope

To meet the requirement of framing diagnosis of CH cylindrical target implosion experiments, a four-channel 4.75 keV KB microscope was developed. The optical structure and imaging quality of the four-channel KB microscope were analyzed. With the size limit of framing camera taken into account, the problem of assembly of the four-channel KB microscope has been solved using reference cone core. The assembly and alignment experiments of the four-channel KB microscope were performed in the laboratory. The clear image of four-quadrant grid with a spatial resolution of 3 m in central field was obtained in Shenguang-Ⅱ laser facility, and the image spacing meets the design requirements, indicating that inertial confinement fusion framing experiments could be carried out.
