| 摘 要： | 为了研究柱腔内气体对激光-等离子体相互作用及内爆对称性的影响，详细给出了气袋靶制备及其在神光-Ⅱ靶场的应用情况。对气袋靶的靶型设计、靶材料选择及薄膜制备和充气工艺进行了系统的研究。制备的气袋靶主要由厚度为400 nm的聚酰亚胺薄膜和厚度为400 m的铝支撑环构成，利用装配在支撑环上的充气管实现对气袋靶的充气，当充气完成后，整个气袋靶膨胀为球状。

| Abstract: | To study the effect of hohlraum gas on both laser-plasma interaction and implosion symmetry, the paper presents the design, material selection and fabrication of gas bag target, the filling gas technology and the implementation of the target on the Shenguang Ⅱ facility. The gas bag target is made by gluing two 400 nm thick polyimide films to a 400 μm thick aluminum (Al) washer. The target is inflated with gas through a small filling tube mounted into the aluminum washer and the polyimide is stretched to a near-spherical shape. |
