U125-2_NIM beamline

Normal incidence monochromators (NIM) are typically used in synchrotron beamlines which are dedicated to experiments operating in an energy range of about 4 to 35 eV only. The decisive advantages of this type of monochromator design are that only small aberration errors occur and highest resolution can be easily achieved with it.

The 10m-NIM beamline (Reichardt et al. 2001) was designed for the undulator U125-2 (Bahrdt et al. 2001) and is based on the so called off-Rowland circle mounting design (Samson 1967). This implies that the grating has to be rotated and slightly translated in order to get the highest resolution and a small spot size in the experiment.
