ABSTRACT
This beamline is dedicated to macromolecular crystallography in monochromatic X-ray mode. White X-rays from the standard "B2" type bending magnet are monochromatized with a fix-exit double crystal monochromator (DCM) then focused with a 1-m-long platinum-coated bent-cylinder mirror. The glancing angle (2 ∼ 5 mrad), the radius of curvature (3000 ∼ 7000 m), and the vertical position (±15 mm) of the mirror are adjusted for the optimum focusing at the sample position (see the optical layout). The photon flux at the sample position is estimated to be 1.1×1011 photons/sec at 12.4 keV with tha beam size of 0.22×0.20 mm2 (FWHM).
