Abstract
A fluorescence X-rays radiation device is established. The device is mainly composed of X-rays machine, fluorescent radiator, secondary filter and beam-limiting diaphragm. It can generate monochromatic X-rays with 8 energy points below 100 keV. The flux is about 106 photon/s. An HPGe detector for X-rays energy spectrum measurement were calibrated using standard radioactive sources, and the relationship between energy and channel was obtained. The Monte Carlo simulation software was used to simulate the detector detection efficiency curve. The primary and secondary radiant energy spectra of the fluorescent radiation device were measured using the HPGe detector, and the fluence rate and energy resolution of the radiation device at different energies were obtained.
