A small angle neutron scattering instrument is currently being designed at the University of Missouri Research Reactor. An anti-parallel arrangement of two Ni-Ti multilayers will serve as a neutron monochromator for this instrument. The first multilayer will be flat and in soller, or transmission, geometry. The second will be curved and in the conventional reflection geometry. The curvature of the second multilayer is designed to eliminate resolution asymmetry and increase the incident neutron intensity. The intensities are still too low with this arrangement, but can be increased two or threefold by depositing a second or third bilayer group with a spacing slightly offset from the first group.
