A new 4 meter normal incidence monochromator (NIM) has recently been commissioned at the Synchrotron Radiation Center (SRC). The beamline utilizes two indexing spherical gratings to cover the energy range of 6–50 eV. A resolution of 0.35 meV at 15.765eV has been measured, which agrees well with the theoretical value. The source for the beamline is a 3.5 m long, 10.9 cm period electromagnetic undulator. The device can be scanned through the full energy range at any time with beamline based controls. © 2000 American Institute of Physics.

    Many monochromators rely on quadrature encoders for positioning optical elements like gratings or mirrors. In most cases the required accuracy is significantly higher than the pitch of the encoders and an interpolation scheme becomes necessary. The accuracy of this procedure can be significantly...
