The polarization purity of 6.457- and 12.914-keV X- rays has been improved to the level of 2.4E-10 and 5.7E-10. The polarizers are channel-cut silicon crystals using six 90° reflections. Their performance and possible applications are demonstrated in the measurement of the optical activity of a sucrose solution.

Keywords: X-ray polarimetry; diffraction; channel-cut silicon crystal
