Extract

The pioneering work of Marra, Eisenberger and Cho (1979) demonstrated that powder diffraction from near surface and interfacial regions could be obtained using glancing incidence geometry. This has generated considerable interest in research at synchrotron sources, but also several slit attachments have been developed for commercial diffractometers. By adding a focussing mirror, we demonstrate here a simple arrangement that produces adequate intensity with a sealed tube to examine ultra thin films.
