Abstract Accepted
In ICF study ,the implosion is very important which concerns too many physical process ans is the research emphasis. The hot-spot state,temperature and density are the critical quantity to estimate the ignition threshold. In addition, the hot-spot state also reveal performance of drive symmetry. The analysis of symmetry is the important means to tune the implosion compression. The 2D X-ray imaging is used to measure the hot-spot self-emission. The symmetrical feature is obtained by using post-processing with X-ray images which characters the symmetry of driving and can be used to offer the experimental references. However the hot-spot is the 3D X-ray emitter. The comprehensive analysis of 3D emission and symmetrical information of hot-spot contain more information than by only using 2D X-ray image of hot-spot. Therefore, the diagnosis of 3D emission of hot-spot is highly necessary. In experimenting we can only obtain the 2D emission of hot-spot. That is, the projections of hot-spot can be measured whit different directions. Multi-angle imaging is use to reconstruct the 3D of hot-spot self-emission with reconstruction algorithm. And overall compression of hot-spot can be obtained by these 3D reconstruction of hot-spot. In this paper we use high spatial-resolution Kirkpatrick-Baez(KB) X-ray microscope to measure hot-spot self-emission in two orthogonal directions and two x-ray images of hot-spot in two different energy region are obtained. The maximum likelihood reconstruction algorithm is used to reconstruct the 3D hot-spot emission. These 3D reconstruction images provide more information about the symmetry of compression of implosion and established the base for analysis of 3D compression of hot-spot. Fig1 shows the reconstruction of 3D hot-spot emission in two different energy region.
