材料可压缩性和材料熵对于惯性约束聚变研究具有重要意义。在神光系列激光装置上，研究了双冲击压缩条件下材料压缩过程中的预热退化问题。对比了不同桩柱功率下的后表面膨胀偏差和多次冲击正时偏差。除了激波外，测量的预热还可以提供更多的物理边界和实验基准。为了保持烧蚀/燃料界面的稳定性，在双冲击压缩下，Pickket=9.60TW，Tr=146 eV，必须添加1%的硅掺杂。而纯GDP烧蚀适用于Pickket=3.36TW。这项研究展示了一种新的试验台，为内爆实验提供现场预热评估。它的目的是验证双激波、低收敛比设计的预热水平及其对材料压缩的影响。它还可以为靶材掺杂剂的设计和即将到来的冲击调谐过程提供有价值的信息。
Material compressibility and entropy is of great significance for inertial confinement fusion research. Preheat induced degradation on material compression under double shock compression is studied on ShenGuang series laser facility. The deviations on rear surface expansion and multiple shock timing are contrasted under different picket power. The measured preheat besides shocks could provide more physical boundaries and benchmarks from experiment. 1% silicon dopants is mandatory to keep ablator/fuel interface stable with Ppicket=9.60TW and Tr=146eV in a double-shock compression. While pure GDP ablator is applicable to Ppicket=3.36TW. This study demonstrates a new testbed to provide in-situ preheat evaluation for implosion experiment. It aims to validate the preheat level and effects on material compression for a double shock, low convergence ratio design. It could also provide valuable information for target dopant design and upcoming shock tuning process.
