Abstract

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, Cs I (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.

摘要

采用X射线管和光谱仪研制了一台X射线激发荧光光谱仪。对所选用的X射线管、光谱仪、自动控制方法和数据处理进行了全面评估。用汞灯和溴化钨标准灯对该仪器的波长和探测效率进行了校准，并测量了BaF2、Cs I（Tl）晶体的X射线激发发射光谱。结果表明，该仪器具有波长分辨率好、稳定性高、操作简便、辐射防护好等优点。它是探索新型闪烁材料的一种非常有效的工具。
