Si(511) channel cut for monochromatization and linear polarization of X-rays

The capabilities of an Si(511) channel-cut monochromator used with an X-ray tube with copper anode are presented. By passing this Si(511) channel-cut crystal, X-rays become both monochromatic and linearly polarized. The monochromaticity of the resulting beam is proved by angular dispersive measurements. Elastic scattering was used to characterize the degree of linear polarization.
