摘要
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。
Pellet injection and ablation are observed in the HL 1M tokamak with a high speed 2D CCD camera.A large number of multi frame and multi exposure pictures of ablation cloud with high time resolution (exposure 0.1μs) are obtained during one discharge,and the q profile of the HL 1M plasma is measured.The experimental setup,main problems and the result of q profile measurements based on cloud inclination angle observation are described.The effect of pellet injection is analyzed by means of the pictures,and the physical mechanism of pellet plasma interaction is discussed.
