(a) High-resolution set-up used at the CHESS A2 wiggler beamline to measure `intrinsic' reflectivity curves from high-resolution MLs. The Si(111) monochromator defines the energy of the beam and the pair of Si(004) double-bounce channel-cut crystals in a non-dispersive geometry provides 4.1 arcsec angular resolution. Ion chambers IC1–IC4 monitor the beam intensity along the optical path. (b) Experimental rocking curve measured from an Al2O2/B4C multilayer with 800 bi-layers and d = 27 Å measured at 10.0 keV. The FWHM (full width at half-maximum) width of the curve is 10.5 arcsec.
