Abstract:
A crystal bender for sagittal focusing has been designed for standard monochromators at SPring-8. The bender does not move the position of the crystal center when the bending radius is changed. Sagittal focusing from 40 keV to 60 keV was achieved by using Si(311) double crystals. The flux density of the focused beam measured at 40 keV was 15 times higher than that of the unfocused beam. The height deviation of the focused beam throughout the measured energy range was within +/- 0.15 mm.
