在 HL- 1M装置上用高速二维成像 CCD相机观测了弹丸的注入和消融过程 ,获得了一次放电的大量高时间分辨率 (曝光时间为 0 .1μs)的多幅多次曝光的弹丸消融云照片 ,并对 HL-1M等离子体的 q分布进行了初步测量。描述了基于消融云倾斜角观测进行 q分布测量的实验布局、基本问题和结果。根据照片分析了弹丸注入效果 ,讨论了弹丸与等离子体相互作用的物理机制。 The injection and ablation of the projectile were observed on a HL-1M device with a high-speed two-dimensional imaging CCD camera to obtain a large number of multiple-shot projectile-ablation clouds with a high time resolution of 0. 1 μs with one discharge Photographs and a preliminary measurement of the q-distribution of the HL-1M plasma. The experimental layout, basic problems and results of q-distribution measurement based on the observation of tilt angle of ablation cloud are described. Based on the photographs, the effect of projectile injection was analyzed, and the physical mechanism of the interaction between projectile and plasma was discussed.
