Abstract

Abstract

Based on K fluorescence X-rays, the diffraction efficiency experiments of LiF220 crystals at 23.3 keV and 31 keV energies were carried out, and the Bragg angle of the incident single-energy X-rays was adjusted to measure the diffraction single-energy X-rays, and the experimental results showed that the crystals could obtain relatively complete diffraction peaks under the two energies. Under the irradiation of 23.3 keV and 31 keV, the maximum diffraction efficiency is about 2.46% and 1.33%, which is consistent with the theoretical value, when the incident angle is 10.8° and 8.1°, respectively. 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. It provides a tool to test experimental conditions and data interpretation, ensuring reproducibility and reliability of the study.
