为了利用X箍缩产生的点光源作为背光光源对丝阵Z箍缩内爆早期的负 载内部结构进行背光照相, 在阳加速器(电流峰值为500800 kA, 上升时间约80 ns)上开展了钛丝(丝交叉角度为60) X箍缩光源辐射特性的初步实验研究. 通过X射线二极管探测器、透射光栅谱仪、晶体谱仪和狭缝相机等诊断设备获取了箍缩点光源的辐射功率达到1.5 GW左右, 辐射能量约为1 J, 光子能量为keV量级的辐射能谱范围主要集中在14 keV能段, 点光源尺寸小于15 m, 其时间尺度(辐射脉冲半高宽)达到了200 ps. 对光源特征信息进行了初步分析, 同时掌握了有效获取钛丝X箍缩单脉冲点光源的方法.The X-ray radiation properties of titanium wire X-pinch are investigated on the Yang accelerator at 500800 kA peak current with a rise time of about 80 ns. The radiation power, spectrum and source size of the X-pinch X-ray source are measured and analyzed using X-ray diodes, a transmission grating spectrometer, a crystal spectrometer and a slit camera. The hot dense spot smaller than 15 m emits 1 J of X-ray with an FWHM of 200 ps and a peak power of 1.5 GW distributed in the range of 14 keV. A method to efficiently generate a single X-ray pulse during the X-pinch implosion is demonstrated. The X-pinch presented here is useful for imaging the early stage interior structure of Z pinch as a backlight source.
