研制了高精度在线准直、超宽光谱范围和高能谱分辨的在线凸圆柱面弯晶谱仪.使用耦合针状CsI(Yl)闪烁体的大面阵CMOS相机对X射线光谱进行在线测量,用QTZ(1010)(2d=0.851 2 nm)X射线晶体的能谱测量范围是1.84 ～7.38 keV,能谱分辨880@2.375 keV,动态范围≥1000.在神光-Ⅲ主机高功率激光装置上,对钛激光等离子体发射的X射线谱进行实验测量,获得了优质的光谱图像;对钛离子X射线精细结构光谱进行了辨识,与理论计算和其他实验结果吻合.该谱仪用于神光-Ⅲ主机通用诊断搭载平台,具有抗瞬发超强电磁脉冲干扰能力,工作稳定.“,”The convex crystal spectrometer,consists of a convex crystal and CMOS camera which assembles CsI(T1) scintillation,has been designed and fabricated to record X-ray spectra in the energy range of 1.84-7.38 keV by QTZ (1010) (2d=0.851 2 nm) X-ray crystal at one shot.The spectral resolving power was 880 at 2.375 keV,dynamic range of at least 1 000.This spectrometer has characteristics of online aiming,high resolving power,and wide energy range and less noise counts.At Shenguang-Ⅲ laser facilities,soft X-ray spectroscopy from Titanium laser-produced plasmas was obtained by the spectrometer,main lines of Titanium ions have been identified in the excellent agreement with theoretical calculation and other experiment results.On the DIM of Shenguang-m laser facilities,the spectrometer can work stably and adapts to the over loading electron magnet pulse environment.
