- The effect of resonance, observed in X-ray waveguide layered structures in a characteristic way influences the scattering properties of the films. It is well known that in the resonant region the reflectivity shows a series of minima, usually very deep and extremely narrow. The positions and depths of the minima depend only on X-ray waveguide structural properties, on the X-ray wavelength and on the incident beam divergence. In the present work we propose and discuss the application of the X-ray waveguide and quasi X-ray waveguide film structures as tools to experimental evaluation of some quantities related to X-ray reflectometric or diffractometric measurements, like the beam divergence, wavelength, or angular distance. Examples of application of the X-ray waveguide as an excellent tool to estimate the effective beam divergence are shown. Properties of the X-ray waveguide elements as a handy wavelength or angular calibration standard are also mentioned.
