Abstract

We have fabricated a bifocal miniature toroidal mirror that horizontally and vertically focuses to two different locations to provide a smaller footprint of the beam for grazing-incidence wide-angle scattering (GIWAXS), while at the same time focusing the beam in the horizontal direction on the detector to further enhance the angular resolution. At CHESS we traditionally use glass single-bounce monocapillary optics for a wide range of X-ray experiments to get a fine X-ray beam of 5 to 20 μm. This miniature toroidal mirror was prepared by designing and fabricating an X-ray focusing capillary in which the sagittal and meridional focusing is decoupled and only a quadrant of the accepted annulus is used for focusing the beam. The mirror produced a 120 μm horizontal by 25 μm vertical focus at 50 mm from the tip of the optic and a 44 μm horizontal by 70 μm vertical focus at 150 mm from the tip of the optic.
