描述了在ＨＬ１ Ｍ 装置上氢弹丸注入时用高速ＣＣＤ 相机拍摄 Ｈα辐射照片的实验结果。得到了弹丸消融云图像、速度及轨迹。通过对照片的处理，获得辐射光强的空间分布。分析了弹丸轨迹发生弯曲及条纹现象，探讨了弹丸与等离子体相互作用的物理机制，为进一步在弹丸注入条件下用ＣＣＤ 测量等离子体局部磁场和电流分布打下了基础 Describes the experimental results of photographing Hα radiation with a high-speed CCD camera at the injection of hydrogen projectile on a HL-1 M device. Projectile melting cloud images, speed and trajectory. Through the processing of the photos, the spatial distribution of the radiation intensity is obtained. The phenomena of bending and fringe of projectile trajectory were analyzed. The physical mechanism of the interaction between projectile and plasma was explored, which laid the foundation for further measurement of plasma local magnetic field and current distribution by CCD with projectile injection
