介绍了软X射线功率测量系统用在中俄联合Z-Pinch实验的C-300装置上,测量软X射线辐射功率和能量,研究辐射功率随时间变化的关系,并为其他测试系统提供时间关联信号。实验中丝阵靶分为单层钨丝阵、铝丝阵和双层铝丝阵,实验结果得到了各种丝阵靶的软X射线辐射波形、辐射功率和能量。其中,双层丝阵的辐射峰分离普遍比单层低,X光辐射的轴向同步性对辐射前沿有明显影响,较快的脉冲前沿可能反映了等离子体内爆均匀性较好,通常产生较高的辐射功率。辐射脉冲宽度与功率没有直接的关系。丝阵负载的微观结构对辐射功率有重要影响,增加丝间隙的均匀性,对改善聚心的同时性,提高功率有明显作用。
The soft X-ray power measurement system is introduced on C-300 unit of Sino-Russia joint Z-Pinch experiment to measure soft X-ray radiation power and energy, to study the relationship between radiation power and time, and to provide time correlation for other test systems signal. In the experiment, the array targets were divided into single-layer tungsten wire array, aluminum wire array and double-layer aluminum wire array. The experimental results obtained the soft X-ray radiation waveforms, radiation power and energy of various kinds of wire array targets. Among them, the separation of the radiation peaks of the double-layer wire array is generally lower than that of the single layer, and the axial synchronization of the X-ray radiation has a significant effect on the radiation front. The faster pulse front may reflect the better uniformity of the plasma implosion, High radiant power. Radiation pulse width and power are not directly related. The microstructure of the filament array load has an important influence on radiant power, increases the uniformity of the filament gap, and has a significant effect on improving the concentricity of the centripetal and increasing the power.
