高增益靶体点火的动力学过程分析

THEKINETICPROCESS ANALYSIS OF VOLUME THERMONUCLEAR IGNITION IN HIGH GAIN INERTIAL CONFINEMENT FUSON

摘要: 针对中心热斑点火和热核传播燃烧(简称中心点火)的高增益靶设计理论要求很高和技术上的难度很大,我们通过阻热层的设计,在高增益靶的整体点火和燃烧(简称体点火)设计上首先实现挡光系统的非稳定温度脱离,由平衡点火和燃烧逐步过渡到非平衡点火和燃烧,从而将驱动能量降到15MJ左右,实现了体点火和体燃烧,并达到了可观的增益。

Abstract: A good heat-resistance layer and a good inert layer as the shell of DT are used to make volume ignition and volume burn (VIVB) realistic.An unstable non-LTE state and the transition from LTE ignition and burn to non-LTE ignition and burn is discussed, and in this way the volume ignition and volume burn design is achieved and high gain fusion is obtaind.
