An imaging system is assembled based on a very fast (18,000-40,000 frames per second) video camera and an arc lamp producing a large-area, collimated, high-intensity beam. The equipment will be used in studies of arc-anode attachment instabilities, the mechanism of droplet formation in wire arc spraying, a reacting countercurrent shear layer in a combustor configuration, and cathode erosion mechanisms for very-high-current plasma torches.

成像系统是基于一个速度非常快(每秒18,000-40,000帧)的摄像机和一个产生大面积、准直、高强度光束的弧光灯组装而成的。该装置将用于研究弧阳极附着不稳定性、丝弧喷涂熔滴的形成机理、燃烧室结构中的反应性逆流剪切层以及超大电流等离子炬的阴极侵蚀机理。
