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。
The pinhole camera with X-ray streak camera and Faraday cup was used to observe the motion characteristics of the cavity target plasma, the inhibition of high-Z high-density plasma motion by the CH wall film in the cavity wall, and the influence of the isolation film on the plasma expansion. The corresponding electron temperature of thermal plasma in cavity was calculated by hard X - ray spectroscopy and shortwave of stimulated Raman scattered light. These results contribute to the further study of the characteristics of the target radiation field under the 0.35μm laser irradiation and the design of the target structure of SGSⅡ.
