What recent literature (review articles prefered) on constructing the optics for a small angle scattering station at a bending magnet beam line can you recommend? The issue is to design the optics of a SAXS beam line at a 2.5 GeV storage ring that should allow to do Anomalous SAXS (e.g. on metal alloys), and as usual without squandering too many photons. I am thinking about an optics with a DCM utilizing a saggitally focusing crystal, and with a meridionally focusing mirror (no ellipsoid or toroid, due to very limited budget), but there are problems: 1) poor Q-space resolution, esp. in the horizontal, when I gather too much flux in the horizontal (-> find a compomise) 2) radius of curvature of the crystal has to change with the energy. Hints on proven solutions would be greatly appreciated. Gernot Buth (buth@anka.fzk.de)
