摘　　要：软X光能谱仪（SXS）是惯性约束聚变黑腔辐射流、辐射温度测量的主要诊断设备。根据神光Ⅱ升级装置实验需求，完成软X光谱仪系统研制，并开展了性能研究。谱仪采用环形透镜成像准直方法保证瞄准精度，通过固定角度平面镜安装机构来减少角度偏差。利用滤片、平面镜以及X光二极管（XRD）探测器的标定实验结果，得到谱仪测量能区为0．05～4．97keV。在短脉冲激光装置上开展通道时间响应性能研究，确定系统时间分辨力为99．22ps。Soft X-ray energy spectrometer （SXS） is an important instrument for radiation temperature measurement. According to Shenguang Ⅱ-up experimental requirements, the 15 channel soft X-ray energy spectrometer has been developed and its performances have been studied. The spectrometer＇s structure has been improved. Circularity convex has been used to image the target for precise collimation, and angle changeless setup has been adopted to avoid mirrors angle error. Filters, mirrors and X- ray diodes （XRDs） have been calibrated on synchrotron radiation facility. The results show that SXS spectrum range is 0.05-4.97 keV. And the temporal performances have been studied on the short-pulse laser facility. The temporal resolution achieves to 99. 22 ps.
