Experimental studies of the argon-puff Z -pinch implosion process

A preliminary experiment for studying the argon-puff Z-pinch implosion process has been performed on the Yang accelerator. The ten-frame nanosecond temporal and spatial gated camera，visible high-speed scanning camera, differential laser interferometer, X-ray time integration pinhole camera and X-ray power system have been used to investigate the evolution of the argon-puff Z-pinch. Some typical results of argon-puff Z-pinch during implosion and pinch phase, including the “zipper” effect, necking phenomenon, sausage instability，temperature changes and the effect of load current rise time, are given and analyzed as examples, and some relevant conclusions are drawn.
