Abstract

A new single crystal focusing monochromator for protein crystallography has been developed. In order to achieve simultaneous tuning of the beam demagnification rate and the radius of curvature for focusing over a wide wavelength range, an inclined monochromator was cylindrically bent. The monochromator has an ability to tune such two parameters simultaneously with an azimuthal rotation of the crystal. A new monochromator incorporating this idea has been developed for beamline BL6B at the Photon Factory. The monochromator was designed for use in a wavelength range 0.87 Å to 1.90 Å. The evaluation of the beam focusing was performed at wavelengths of 1.04 Å, 1.38 Å and 1.74 Å.
