摘要: The main results of investigation on the tungsten wire array Z-pinch implosion experiment performed on Qiang-Guang I facility in 2003 are reported in this paper. A set of diagnostic equipments including an x-ray power meter (XRPM), a 1D spatial-temporal x-ray meter and a pinhole camera was used to study implosion process and x-ray radiation characteristics of the tungsten wire array. In the experiment, the maximum x-ray yield of 36.6kJ was obtained for an optimizing load with a diameter of 8mm and a length of 20mm, which consists of 32 5-μm-diameter tungsten wires. The experimental results show that the region of x-ray emission decreased at a rate of 6.4×106cm/s by analysing the data of the 1D spatial-temporal x-ray meter. It also shows that the peak time of x-ray radiation was prior to the time when plasmas were compressed into a near-axis region.
