脉冲强电流Z箍缩等离子体的理论研究

ONEDIMENSIONAL SIMULATIONS OF Z-PHICHELECTROMAGNETIC IMPLOSION PLASMA

采用简化的一维模型，对脉冲强电流Ｚ箍缩内爆等离子体过程进行了总体数值计算。计算结果和ＢＬＡＣＫＪＡＣＫ５实验装置的测量值进行了对比。两者相比表明，主要物理量的差别在１０％以内，因此该方法可以作为实际装置物理方案设计和实验结果分析的一种工具。

The generation of pulsed highenergydensity plasma by electromagnetic implosion of cylindrical gas shell (i.e.,hollow Z pinches)has been investigated theoretically using a onedimensional code proposed here.The main mechanism of EM implosion process involves hydrodynamics,radiation in the collapsing plasma,and equation of LR circuit.The discrepancy between the numerically computed results and the experementally measured results is found to be less than 10%.It is shown that this code can be used as a tool to design new EM implosion device.
