摘要
研制的透射光栅谱仪配备了高线密度金透射光栅作为分光元件,使用X光CCD记录时间积分光谱图像。在谱仪结构中引入了两个相互垂直的狭缝,一个用于实现光谱图像的1维空间分辨;另一个与光栅相配合后具有准直入射X光的作用,用来提高谱仪的分辨力。使用该谱仪对“阳”加速器Z箍缩实验的X光辐射进行了测量。当使用铝丝阵作为负载时,测得了铝的K壳层辐射和类锂离子的线谱辐射,并且通过将光谱图像与X光针孔相机的测量结果相比较,观察到了“热点”区域放出的较强的K壳层辐射。
Abstract
A transmission grating spectrometer has been fabricated for the study of X-ray radiations from Z-pinch plasma. The spectrometer contains a 3 333 lp/mm gold transmission grating and an X-ray CCD to record time-integral spectral images. Two slits are employed in the spectrometer. One is used for 1D space resolving and the other,working together with the grating’s entrance slit,can collimate the incident X-rays and thus improve the spectral resolution of the spectrometer. The spectrometer has been used in Z-pinch experiments performed on Yang accelerator. When using Al wire arrays as Z-pinch loads,the Al K-shell lines and lines from Li-like ions were observed. In addition,by comparing the spectral image with the image obtained from an X-ray pinhole camera,the K-shell radiations emitted from the “hot spot” region were recorded.
