Abstract:
In the field of indirect-drive inertial-confinement-fusion, to acquire high spatial resolution X-ray radiation images is the foundation for hydrodynamic instabilities and imploded process researches. Kirkpatrick-Baez (KB) microscope, which is based on the principles of grazing-incidence X-ray imaging, is an X-ray diagnosis device presenting an extra-high spatial resolution and a big total solid angle of collection. The KB microscope has been an international key X-ray diagnosis device on ICF facilities. We have investigated KB devices on SG-Ⅱ and SG-Ⅲ prototype facilities and made remarkable progresses on optical design, optical component preparation and assemblage technology of objective mirrors. A large object-field KB microscope and a multi-energy KB microscope have been developed. These KB microscopes have been applied in the hydrodynamic instabilities and implosion experiments, and performed high-resolution high-magnification images of key physical data for laser-fusion plasma research.
