完全稳定化MRT的可能性及应用于聚变的潜力

摘要

提出采用方向时变(旋转)的驱动磁场(交替 Θ-Z箍缩构型)或者多级嵌套 Θ-Z箍缩构型来抑制动态Z箍缩的MRT不稳定性的概念,介绍了对交替/嵌套 Θ-Z箍缩MRT不稳定性的最新研究进展,结果表明适当优化的交替/嵌套 Θ-Z箍缩的MRT不稳定性明显远低于标准 Θ 箍缩或者Z箍缩的,一定厚度时甚至被完全致稳,这表明交替/嵌套 Θ-Z箍缩构型具有潜力应用于 Θ-Z箍缩套筒惯性聚变.%The idea of using a directional time-varying(rotating)driving magnetic field (the alternant theta-Z-pinch configu-ration)or the multi-nested theta-Z-pinch configuration to suppress magneto-Rayleigh-Taylor instabilities in a dynamic Z-pinch was proposed between 2014 and 2016.This paper reports the latest research progress on magneto-Rayleigh-Taylor instabilities in al-ternant/nested theta-Z-pinches.The magneto-Rayleigh-Taylor instability growth of a properly optimized alternant/nested theta-Z-pinch is significantly lower than that of a pure theta-pinch or Z-pinch.The instability is completely stabilized at a certain thickness of the liner.These show the bright potential of alternant/nested theta-Z-pinch for theta-Z-pinch liner inertial fusion.
