摘要

磁通量压缩方案是由Gramat研究中心(CEG)与桑迪亚国家实验室合作研究的。该方案作为超高压等熵压缩材料的脉冲整形方案和X射线产生的功率放大方案进行了研究。实验在两种不同的状态下进行:在桑迪亚的Z发生器上进行100 ns, 15 MA脉冲，在CEG的ECF发生器上进行1 /spl mu/s, 3 MA脉冲。对Z和ECF上的投篮进行了总结。例如，在Z发生器上使用磁通压缩，在铜样品中实现了5mbar的激波，超过2mbar的等熵压缩。仿真结果与实验结果进行了比较。它们允许我们调整代码，以预测实验结果，并提高我们对方案的物理理解。

The magnetic flux compression scheme as a power amplification & pulse shaping stage

The magnetic flux compression scheme is studied at Centre d'Etudes de Gramat (CEG) in collaboration with Sandia National Laboratories. This scheme is studied as a pulse shaping scheme for very high pressure and isentropic compression in material and as a power amplification scheme for X ray production. Experiments have been done in two different regimes: 100 ns, 15 MA pulse on the Z generator at Sandia and 1 /spl mu/s, 3 MA pulse on the ECF generator at CEG. A summary of the shots on Z, as well as on ECF is given. For example, 5 Mbar as a shock, more than 2 Mbar in isentropic compression in a copper sample have been achieved on the Z generator using flux compression. Comparisons between simulations and experiments are presented. They allow us to tune the codes in order to predict the experimental results and improve our physical understanding of the scheme.
