Abstract The flux spectrum produced by X-ray tube is indirectly measured based on the absorption method. Based on this, the principle of unfolding is clarified, and combined with the response function and presetting spectrum, the unfolding of 100kV X-ray toughness radiation spectrum is completed by the unfolding program, and its mean energy is calculated to verify the accuracy of the unfolding results. Compared with the mean energy result calculated by numerical analysis software, the error between the two is 14%. And the reason for the error between the pulse amplitude spectrum and the X-ray flux spectrum has been analyzed.
