SCATTER SPECTRA METHOD FOR X-RAY FLUORESCENT ANALYSIS WITH OPTICAL COMPONENTS

摘要

A method of measuring the transfer function of an X-ray optical component over a wide range of X-ray energies, which includes the steps of:using an X-ray optical component between an X-ray source and a scattering target to obtain a first scatter spectrum;obtaining a second scatter spectrum from the same or a similar target without the X-ray optical component between the X-ray source and the scattering target; andcalculating the transfer function by the ratio of the first scatter spectrum to the second scatter spectrum. The method can be used to improve the accuracy of X-ray quantitative methods in an apparatus where an X-ray optical component is used between the X-ray source and the specimen to be investigated by utilizing the method described above.
