The method of 3D phase‐space analysis is used to optimize the design of a double‐focusing small‐angle scattering camera with mirror/monochromator optics. Radiation from the 0.1 × 0.1 mm focal spot of a rotating‐anode generator is focused in the vertical direction by an elliptical Ni‐covered mirror and in the horizontal direction by an asymmetrically cut cylindrically bent Ge(111) crystal. The total length of the camera is about 4 m. The implementation of monochromator/multilayer optics is also discussed.
