The new backscattering spectrometer RSSM for the FRM-II reactor uses all possibilities to optimize this type of spectrometer. In its high-intensity version it uses unpolished Si(l 11) crystals. The good energy resolution of deltaE less than or equal to 0.9 mueV is achieved by staying as closely as possible at a Bragg angle of 90degrees not only at the Doppler monochromator in the primary spectrometer but also at the analyzer system of the secondary spectrometer. The large solid angle of the analyzer system compensates the low intensity which is a result of the good energy resolution.
