In November, 2007 we had a second week of beam time at CHESS in Cornell University. We set up a new asymmetric monochromator that expands the beam vertically to about 1.5 cm. The monochromator design is described here. It is dispersion-matched to the diamond 220 reflection. We measured rocking curves for several good diamond crystals (100 microns thick) during this run and demonstrated rocking curve resolution better than 10 μr RMS.
