Notes:
Small alignment errors of right-angle linkage monochromators typical to many x-ray absorption fine structure beamlines can cause significant errors in the energy calibrations. A 1° misalignment produces errors greater than 1 keV over the hard x-ray operating range of a typical monochromator. The energy error caused by such misalignments is analyzed and its mathematical form given. The error can be corrected by inverting the expression and the amount of misalignment determined by accurate energy measurements at a few points. The accuracy of the corrections is tested. The effects of this error on x-ray absorption fine structure data and their interpretation are also discussed.
