摘要
X射线衍射仪的校准是保证仪器准确测量的重要工作,但是仪器厂家并没有提供给用户详细校准方法。根据对仪器光学系统和工作原理的分析,设计了使用荧光板对X射线衍射仪进行校准的方法,并依据JJG 629-2014《多晶X射线衍射仪检定规程》对校准后的仪器进行了2θ角示值误差,2θ角分辨力和2θ角重复性检定。结果表明,该方法适合X射线衍射仪的校准工作。
According to the analysis of the optical system and working principle of the instrument,the method of calibrating the X-ray diffractometer with a fluorescent plate is designed.According to the verification regulation of polycrystalline X-ray diffractometer(JJG 629-2014),the calibrated instrument is calibrated for 2θangular indication error,2θangular resolution and 2θangular repeatability.The results show that this method is suitable for the calibration of X-ray diffractometer.
