AbstractWe report on integrated simulations of hohlraum targets based on the new code MULT12D for two-dimensional radiation hydrodynamics. Targets for heavy ion beam fusion with two-sided irradiation are discussed; l = 4 asymmetry is controlled by low-albedo rings in the hohlraum wall. Targets designed for laser-driven shock wave experiments are also presented. MULT12D in its present version is still restricted to the use of simplified (power-law-type) equations of state and opacities, so the results are of semi-quantitative nature. We focus on hohlraum dynamics and aspects of radiation field symmetrization.
摘要我们报告了基于新代码MULT12D对二维辐射流体力学中空腔靶的集成模拟。讨论了用于重离子聚变双侧辐照的靶；l = 4不对称性通过空腔壁中的低反照率环得到控制。还介绍了为激光驱动冲击波实验设计的靶。MULT12D当前版本仍限于使用简化（幂律型）状态方程和不透明度，因此结果为半定量性质。我们重点关注空腔动力学和辐射场对称化方面。
