23 December 2003 Double multilayer monochromator to tailor bending magnet radiation spectrum
Author Affiliations +
A double-reflection multilayer monochromator is being developed at BM5 in order to fulfill two different functions. As a primary monochromator, it provides higher bandpass and higher photon flux than the Si(111) Bragg crystal monochromator. In combination with the crystal monochromator, it rejects the harmonics and the beam exit can be kept fixed. An additional aim is to preserve the beam coherence. Design issues and performances evaluated on the beamline are presented.
