Paper Abstract

To fill the gap in energy resolution dE/E between a few percent for multilayer x-ray optics and a few 10-4 for perfect crystal optics we have developed narrow bandpass multilayers consisting of Al2O3 and B4C layers. Their resolving power was precisely determined on the ESRF bending magnet beamline BM5 using a white beam and a Si(111) analyzer crystal. Scans in the (n,+m) and in the (n,-m) scattering geometry return consistent results. With a sample of 680 double layers we have obtained a spectral resolution of 0.27% at energies around 12 keV which is in good agreement with earlier studies using monochromatic x-rays.
