Abstract: This thesis presents the design concept of a novel multi-mirror focusing scheme to condense the x-ray beam emitted from synchrotron radiation sources. The design of the x-ray optic is based on advanced microfabrication techniques and studying of the synchrotron photons distribution in phase space. This x-ray condensing device consists of a group of small mirrors. These small mirrors split a wide x-ray beam into many small beamlets, and each mirror captures and reflects a small beamlet of the x-rays. The whole beam is intercepted and focused to a common focus portion by portion. The position, inclination and curvature of each individual mirror are determined by using the design procedure and formulas developed in this thesis. All mirrors work in the principle of x-ray total external reflection and provide a cost-effective means to produce a bright x-ray beam that substantially improves the capture of x-ray flux in the beamline as compared with conventional x-ray condensing elements.
