Two monochromators for high‐energy synchrotron radiation have been studied at the elliptical multipole wiggler beamline BL08W of SPring‐8. Both monochromator crystals are bent and indirectly water‐cooled. In the 100 keV monochromator an efficient cooling scheme is employed. A monochromatic beam is successfully focused using new benders for the 100 keV and 300 keV monochromators. Measured radii of curvature of the bent crystal agree qualitatively with calculation.
