摘要

利用二维(2D)辐射磁流体动力学(RMHD)数值模拟,我们设计了一个可行的z-pinch辐射源,在z-pinch驱动的双端热腔概念中点燃高产量燃料舱。z-pinch由嵌套的铍(Be)壳和同轴圆柱形泡沫转换器组成。z-pinch的设计目的是产生一个形状的辐射脉冲,通过连续三次冲击来压缩胶囊,而不会显著增加熵。我们给出了与z-箍缩设计有关的模拟结果,并讨论了在z-箍缩中必须达到的条件,以确保产生所需的辐射脉冲。

Z-Pinch Requirements for Achieving High Yield Fusion Via A Z-Pinch Driven, Double Ended Hohlraum Concept
Using two-dimensional (2D), radiation magnetohydrodynamics (RMHD) numerical simulations, we have designed a feasible z-pinch radiation source that ignites a high yield fuel capsule in a z-pinch driven, double ended hohlraum concept. The z-pinch is composed of nested beryllium (Be) shells and a coaxial, cylindrical foam converter. The z-pinch is designed to produce a shaped radiation pulse that compresses a capsule by a sequence of three shocks without significant entropy increase. We present results of simulations pertaining to the z-pinch design, and discuss conditions that must be achieved in the z-pinch to ensure production of the required radiation pulse.
