碩士 === 國立交通大學 === 工學院加速器光源科技與應用碩士學位學程 === 101 === This thesis mainly uses the theoretical simulation, given by Stetsko, to design high performance X-ray multiple cavities of silicon and sapphire. There are two ways to reach the goal : One is to combine two Fabry-Perot cavities with appropriate crystal thickness and gap, so that the cavities have high finesse[1] and high transmissivity simultaneously; the other is to Investigate the resonant behavior of three-crystal plate cavity with the ratio of crystal thickness 1:1:1 and 1:2:1 utilizing the idea from the [X.- R. Huang, Phys. Rev. Lett. 108, 224801 (2012)]. In addition, for the purpose of making an x-ray incident on the cavity to fulfill the condition of resonance, the thesis also design a four-crystal high resolution monochromator at 8.5146 keV and 14.3147 keV respectively.
