Abstract

A new cost-efficient sputter-slice technology for hard x-ray ( 10 30   keV ) Fresnel zone plates fabrication, imposing no limitation to aspect ratio, is proposed. By means of a plasma chemical process, SiO 2 / Si 1 x G e x O 2 glassy film multilayer structures are deposited on a lateral surface of a silica rod, outermost layers being as thin as 100   nm . It has been shown by numerical simulation that for x = 0.2 germanium fraction, 100 300 μ m zone plate thickness and the number of zones of about 1000, first order diffraction efficiency as high as 20%–30% at the energy of approximately 20 keV can be achieved.
