在“阳”加速器上进行了直径分别为10,15,20μm,交叉角为32°,45°,60°的钼(Mo)丝X-pinch实验。“阳”加速器产生的电流峰值约520 kA,上升时间80 ns。实验中通过X射线功率谱仪和纳秒分幅相机等仪器对Mo丝X-pinch辐射特性进行了诊断。实验表明:Mo丝X-pinch过程中会出现多次X射线爆发,箍缩过程中产生的热点辐射出能量超过3 keV的X射线,探测到的最小热点直径小于30μm。 The molybdenum (Mo) wire X-pinch experiments with diameters of 10, 15 and 20μm and cross angles of 32 °, 45 ° and 60 ° were carried out on the “Yang” accelerator. The “positive” accelerator produces a current peak of about 520 kA with a rise time of 80 ns. In the experiment, X-ray power spectrometer and nanosecond fractional cameras were used to diagnose the X-pinch radiation of Mo wire. Experiments show that there are many X-ray burst during Mo wire X-pinch process. The hot spots in the pinch process radiate X-rays with energy exceeding 3 keV, and the smallest detected hot spot diameter is less than 30μm.
