In this paper studies of neutron diffraction properties of the double crystal (+n,-m) setting of a bent perfect crystal Si(311) in the fully asymmetric diffraction geometry with the output beam compression and the bent perfect crystal Si(220) in a symmetric diffraction geometry, are presented. The properties of the (+n,-m) setting were studied for different curvatures of the individual crystal slabs. It has been found that after a beam condensation this fully asymmetric diffraction geometry can provide a monochromatic beam of a small width and of a practical use.
