Experimental study of parallel multi-tungsten wire Z-pinch

The study of three parallel tungsten wire loads and five parallel tungsten wire loads implosion experiment on accelerator “Yang” are reported. Tungsten wires (17 μm) with separation of 1 mm were used. The pinch was driven by a 350 kA peak current, 80 ns 10%~90% rise time. By means of pinhole camera and X-ray diagnostics technology, a non-uniform plasma column is formed among the wires and soft X-ray pulse are observed. The change of load current are analyzed, the development of sausage instability and kink instability, “hot spot” effect and dispersion spot for plasma column are also discussed.
