The Statton camera produces a point-collimated x-ray beam via two pinholes (100 - 500 micron diameter) separated by approximately 15 cm; it employs CuKα x-rays, from the point port of a sealed tube (PANalytical PW2773/20, powered by a PW3830 generator). Monochromatization is achieved with a pyrolitic graphite monochromator (Huber 151) upstream of the pinholes. The camera was designed by W.O. Statton of DuPont in the 1950s to acquire WAXS and SAXS patterns from fibers; our unit is equipped with a hot stage for variable-temperature measurements. Originally designed for use with x-ray film, we have replaced the film with Kodak image plates (storage phosphors). These plates are read with a GE Healthcare Typhoon FLA 7000 scanner, directly yielding a digital scattering pattern with a dynamic range of approximately 105. The near-parallel nature of the x-ray beam conveniently allows for the simultaneous collection of SAXS and WAXS data from the same location on the specimen. Sample SAXS and WAXS patterns are shown below.
