Silicon drift detectors are the core sensors for next-generation space-based X-ray detection, where precise efficiency calibration is crucial for both astronomical observation and radiation monitoring. In this study, calibration was performed using a ground-based monochromatic X-ray calibration facility that employs Bragg diffraction …

The K-fluorescence technique exhibits superior monochromaticity and a uniform radiation field, making it highly suitable for elemental analysis. In this study, a K-fluorescence radiation device was employed to conduct X-ray fluorescence (XRF) analysis on five groups of ancient human bone samples spanning …

As a core tool in precision detection technology, the monochromaticity and flux stability of monoenergetic X-rays directly impact experimental accuracy in applications such as detector calibration. There is an urgent need to overcome the limitations of conventional radioisotope sources (fixed energy) and …
