Realization and Research of Single Energy X-ray Based on X-ray Machine in Low Energy Region

In order to achieve single-energy X-rays in low-energy regions, a single-energy X-ray radiation device based on an X-ray machine was developed. Performance test of the device using HPGe detector, 3keV-30keV single-energy X-rays achieved by the crystal Bragg diffraction principle. The energy spectrum measurement results show that FWHM shows an upward trend with increasing energy. The energy resolution is generally 3%, and the monochromaticity is good. The monochromatic luminous flux is linear with the tube current, the tube current can be adjusted to control the photon flux. Meet the calibration requirements of the detector.
