Abstract：
The synchrotron radiation is focused by using a combined system of a monolithic polycapillary X-ray lens and a toroidal mirror. The synchrotron radiation beam with a 2.3×26mm² area, whose vertical divergence and transverse divergence are appropriately zero and 1.1mrad respectively, is first focused into a beam spot with a 0.9×0.3mm² area, a 0.1mrad vertical divergence and a 1.4mrad transverse divergence by the toroidal mirror. The focused beam spot is then focused by the monolithic polycapillary X-ray lens into a focal spot with a 21.4μm diameter. The gain of power flux density in the focal spot of the polycapillary X-ray lens is 59. At 8.0keV, the transmission efficiency and focal distance of the monolithic polycapillary X-ray lens are 7.9% and 13.3mm, respectively.
