Low-angle synchrotron radiation diffraction with glass-capillary optics.
The use of borosilicate-glass-capillary optics at a chosen wavelength for low scattering has been explored using an undulator beam at the ESRF. With a 2.3 mum beam at 0.092 nm wavelength, a silver behenate powder sample was scanned in two dimensions with a 2 mum step width. Scattering from single crystallites with d(001) = 5.83 nm could be observed. The limit for observation, at low angles, was ca s approximately 0.1 nm(-1) (s = 1/d for d approximately 10 nm).
