A novel crystal bender for x-ray synchrotron radiation monochromators Rev. Sci. Instrum. 73, 1564 (2002;A simple way of characterizing x-ray downwards-deflecting mirror-bender assemblies using the long trace profiler AIP Conf.Design and analysis of the internally cooled silicon mirrors and benders for wiggler sources at the Advanced Photon Source (abstract) Rev. Sci. This paper reports the successful design, fabrication, and testing of several side-cooled silicon and Sic (graphite) synchrotron mirrors (flat, spherical, and cylindrical) with a length of up to 1200 mm. The mirrors are equipped with support structures which allow the mirrors to be bent meridionally to cylinders with radii from infinity to 5000 m. Detailed metrology results are presented for the mirrors and the bending system. All mirrors will be installed at ESRF beamlines 8, 15, and 19. 0 1995 American Institute of Physics.
