Abstract

Abstract

Experimental results of instability developments of 8 mm tungsten wire array Z-pinches on the 1.5 MA level, 100 ns rise-time Qiangguang-Ⅰfacility are presented. The dominated instability wavelength for imploding 8 mm wire arrays in early ablation regime is (0.20.03) mm, and it grows up to longer wavelength in later implosion and stagnation regime. An m=1 kink, when observed, is always on all frames obtained after peak power. Thus there may be some relation between the occurrence of m=1 and the termination of the rapid rise of the power pulse.
