| Abstract: | The transmissivity of aluminium attenuation foils in soft X-ray region can be calculated from their mass thickness and oxide layer thickness that are measured, respectively. In order to verify the result, the transmissivity is also measured directly on Beijing synchrotron radiation facility with the wavelength from 17. 42 nm to 19. 14 nm. The results of two methods coincide within the maximum difference of 11 %. |
