基于邻苯二甲酸氢铊(TAP)弯晶和软X射线分幅相机建立了一套4通道的时空分辨弯晶摄谱仪,测谱范围1 500～2 300 eV,时间分辨约2 ns.分析了谱仪各环节的信号传递和转换过程对系统谱响应的影响.利用该谱仪在"强光一号"加速器(约1.5 MA,80～100 ns)Al丝阵Z箍缩实验中获得了时间分辨及时间积分的Al等离子体K层辐射谱,记录到了类H、类He离子主要共振线及类Li、类He离子双电子复合伴线.将摄谱结果与分能区X射线图像进行了比较.时间分辨的发射谱相对强度与积分结果有明显不同,反映了等离子体在5～10 ns时间尺度上的电子温度和离子布居变化.

A temporally- and spatially-resolved X-ray spectrometer,with spectral range of 1 500～2 300 eV and temporal resolution about 2 ns,has been developed for diagnosing K-shell radiation of aluminum wire array Z-pinch plasma driven by Qiangguang-I generator (1.5 MA,80～100 ns).It consisted of an elliptically-curved TAP crystal and a four-channel X-ray frame camera.Theoretical analyses were made to check out possible effects of different signal transfer and conversion processes on spectral response of the spectrometer.It recorded time-resolved and -integrated K-shell resonance lines of H-,He-like aluminum ions and satellite lines of Li-,He-like ions.Results were compared with spectral-resolved X-ray images obtained by pinhole cameras.Time-resolved K-shell spectra show many differences on line ratios and axial distribution with each other and time-integrated results,which exhibits variations of electron temperature and ion population on a 5～10 ns time scale.
