SAXS / WAXS configurations that allow to easily switch between line and point collimation are described. Using point collimation with a 2D detector enables full-pattern 2D SAXS and WAXS measurements, which is essential for anisotropic materials. The 2D SAXS / WAXS performance is demonstrated on some test samples.
On the Empyrean instrument SAXS and WAXS measurements are usually done with a line collimation setup. Here we describe how such a setup can be quickly and easily transformed to a point collimation setup. Examples of full-pattern 2D SAXS and 2D WAXS measurements from polymers, fibers and colloidal crystals will be given.
