摘要
基于K荧光X射线开展了LiF220 晶体在 23.3 keV和 31keV能量下的衍射效率实验,调整入射单能X射线的布拉格角,测量衍射得到的单能X射线,实验结果显示晶体在两种能量下能够得到较为完整的衍射峰.在能量为 23.3keV与 31keV的射线照射下,分别在入射角度为 10.8°和 8.1°时,得到衍射效率的极大值,约为 2.46%和1.33%,与理论值相符.为材料科学和其他相关领域的研究提供实验数据支持和参考,衍射效率的测量可以用于验证实验结果的准确性,提供了一个检验实验条件和数据解释的工具,确保研究的可重复性和可靠性.
Abstract
Using K fluorescence X-rays,we conducted diffraction efficiency experiments on LiF220 crystals at energies of 23.3 keV and 31 keV.By adjusting the Bragg angle of the incident monochromatic X-rays,we measured the diffracted monochromatic X-rays.The experimental results showed that the crystals produced relatively complete diffraction peaks at both energies.Under irradiation at energies of 23.3 keV and 31 keV,maximum diffraction efficiencies of approximately 2.46%and 1.33%were obtained at incident angles of 10.8°and 8.1°,respectively,which are consistent with theoretical values.This study provides experimental data support and reference for research in materials science and other related fields.Measurements of diffraction efficiency can be used to verify the accuracy of experimental results,providing a tool to test experimental conditions and data interpretation,ensuring the reproducibility and reliability of the study.
