Abstract

Abstract

The state of hot-core in stagnation phase is very important and valuable in inertial confinement fusion. High energy X-ray (70 keV) backlight imaging is the most important method to acquire stagnation phase image. The high energy X-ray is produced by high power petawatt laser facility interaction with high Z metal target. This article was based on Shenguang-Ⅲ laser facility with 483 kJ. Our work analyzed X-ray source flux and implosion noise and proposed a whole design in high-energy X-ray backlight image system. The result indicates that high energy X-ray backlight image is able to obtain stagnation phase image in Shenguang-Ⅲ laser facility.
