Abstract
In Inertia Confinement Fusion (ICF), the symmetry and uniformity of plasma compression are of great importance for plasma diagnostics, which has great significance for in-depth analysis of the physical state in the process of implosion and the high gain ignition parameter design. Most traditional three-dimensional reconstruction methods are based on the symmetric structure, however, potential instability will make plasma to become asymmetry. This paper proposes a novel three-dimensional plasma reconstruction method based on asymmetric layered 3D distribution model. Firstly, with the analysis of the for-ward imaging process of plasma, we put forward a asymmetric layered model and the calculation model of emission coefficient. Then a GA-LS combined algorithm also is adopted for the reconstruction via several pictures of plasma. Numerical simulation result shows high accuracy and robustness of this method.
