通过X射线管与光谱仪的组合， 在对X射线管和光谱仪的选取、 自动控制技术、 数据采集和处理等多个环节进行系统论证的基础上， 自行设计和研制了一台X射线激发发射谱仪。 通过采用标准光源， 对谱仪的波长和效率定标进行了重点研究， 运用这一谱仪分别测量了BaF2和CsⅠ(Tl)等闪烁晶体的X射线激发发射谱。 实验结果表明： 该谱仪具有光谱分辨高、 性能稳定、 操作简便、 屏蔽良好等特点， 可为闪烁材料的探索和开发提供一种十分有效的研究手段。

An X-ray excited fluorescence spectrometer was developed with an X-ray tube and a spectrometer. The X-ray tube, spectrometer, autocontrol method and data processing selected were roundly evaluated. The wavelength and detecting efficiency of the apparatus were calibrated with the mercury and tungsten bromine standard lamps, and the X-ray excited emission spectra of BaF2, CsⅠ(Tl) crystals were measured. The results indicate that the apparatus has advantages of good wavelength resolution, high stability, easy to operation and good radioprotection. It is a wery effective tool for exploration of new scintillation materials.
