摘要: 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500--800kA，上升时间约80ns）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1．5GW左右，辐射能量约为1J，光子能量为keV量级的辐射能谱范围主要集中在1—4keV能段，点光源尺寸小于15um，其时间尺度（辐射脉冲半高宽）达到了200ps．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．Abstract: The X-ray radiation properties of titanium wire X-pinch are investigated on the Yang accelerator at 500-800 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 ~tm 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 1--4 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.
