SRS station 16.3: high-resolution applications

Station 16.3 is a high-resolution X-ray diffraction beamline at Daresbury L aboratory Synchrotron Radiation Source. The data presented demonstrate the high-resolution available on the station utilising the recently commissione d four-reflection Si 1 1 1 monochromator and three-reflection Si 1 1 1 anal yser. For comparison, a reciprocal space map of the two-bounce Si 1 1 1 mon ochromator and two-bounce analyser is also shown. Operation of the station is illustrated with examples for silicon. and for diamond. Lattice paramete r variations were measured with accuracies in the part per million range an d lattice tilts at the are second level (DuMond. Phys. Rev. 52 (1937) 872). (C) 2001 Elsevier Science B.V.
