title: Performance of bent-crystal monochromators for high-energy synchrotron radiation.
abstract: 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.
