0.35μm激光辐照下柱腔靶的等离子体状态与运动特性
-
摘要: 使用针孔相机配X光条纹相机、法拉第杯等观测了腔靶等离子体的运动特性、腔内壁衬CH膜对高Z高密度等离子体运动的抑制现象以及隔离膜对等离子体膨胀的影响。并用硬X光能谱法和受激喇曼散射光的短波截止推算了相应的腔内热等离子体电子温度。 这些结果有助于0.35μｍ激光辐照下腔靶辐射场特性的深入研究以及未来神光Ⅱ腔靶构型的设计。Abstract: Plasma state and motion in gold cylinders, which were irradiated by 0.35(m laser,are experimentally investigated. Some measures suchas CH liner and separate foils to hold back the plasma motion in a cylinder also are tested in experiments.The results obtained may be helpful for control radiation environment in a hohlraum.
