| Abstract: | The characteristics of X-ray lens can be measured by means of the scattering of X-ray. The merit of this method is that the characteristics of X-ray lens in different energy can be measured at the same time. The transmission efficiency and the focal spot size of X-ray lens are measured in this way. The results are compared with the commonly-used method. Therefore the feasibility and superiority of this method is testified through experiment. |
