摘要 平面晶体谱仪是激光等离子体X光光谱重要诊断设备之一,X光光谱的半定量或定量化诊断需要对平面晶体的一些重要参数如积分衍射效率、晶体扭摆曲线半高宽等进行标定。利用北京高能物理研究所同步辐射室的383中能束线作为X光光源,对PET平面晶体进行了实验标定,并对实验标定结果进行了分析,得到了2.1~6.0keV范围内各能点处的晶体衍射效率。实验结果与其它文献符合得很好。 The flat crystal spectrometer is one of the fundamental tools to diagnose X-ray. Quasi-quantitative and quantitative analyses of X-ray spectra require calibrations of the flat crystal's characteristic parameters, such as integral reflective coefficient and FWHM of the flat crystal's rocking curve. Using BSRF 3B3 beam as the Xray source, this article gives an indirect method to calibrate the flat PET crystal. Good results are obtained in the range of 2.1-6.0 keV and interrelated analysis is provided.
