Notes:
The revolver undulator beam line BL-19A at the Photon Factory has been constructed to be dedicated to the solid-state research and laid out for photon energy from 20 to 250 eV. To cover a wide spectral range by the maximum intensity of a first harmonics of undulator radiation, the simultaneous scanning of the undulator magnet gap and the monochromator has been accomplished in the normal user beam time. A displacement of the positron beam induced by scanning the undulator magnet gap are corrected using vertical and horizontal steering magnets at both ends of the undulator. The degradation of the beamline by the high heat loading was considerably reduced by adopting SiC substrate mirrors and gratings.
