Description

Periodic multilayers of W/C and Mo/Si have been developed with magnetron sputtering technology. The parameters of period and thickness are adjusted so that the first Bragg peak appears at the Brewster angle when the photon energy is in the vicinity of K edge of carbon and L edge of silicon respectively. The experiment was implemented at Beijing Synchrotron Radiation Facility (BSRF). The reflectivities of multilayer Mo/Si and W/C can reach 32.3% at 89 eV and 4.18% at 214 eV respectively near the Brewster angle. The feasibility of setting up polarizer with multilayers is discussed in this paper
