Model analysis of experiments of implosion symmetry on Shenguang-Ⅱ and Shenguang-Ⅲ prototype laser facilities
神光-Ⅱ和神光-Ⅲ原型内爆对称性实验的模型分析

The analysis and control of implosion symmetry of fuel capsule is one of the most important issues in inertial confinement fusion (ICF),and many experiments and simulations on it have been done.Here we use a simple model on implosion symmetry in ICF to analyze the best lengths of the hohlraum and distortions of capsule on Shenguang-Ⅱand Shenguang-Ⅲprototype laser facility.It is shown that the calculated best lengths agree with the ones obtained in experiment and the calculated capsule distortions are also close to experimental measurements.The validated model may give some references to the future experiments of implosion symmetry on Shenguang-Ⅲlaser facility.
