Abstract
The combination of an absorption sheet, a high count rate detector and a low-power micro-focus source is used to simultaneously measure the transmission of the polycapillary focusing optical lens in a large energy range. This method places the micro-focus source, the absorber and the detector in a line, has highly operability in actual measurement. The X-rays below 8 keV were completely absorbed when adding the aluminum absorption sheet, and the transmission efficiency of the lens to X-rays below 8 keV was not measured. After the absorption sheet is added, the attenuation of the X-ray is not simply an exponential decay, but also the Compton scattering effect was involved.
