The design and characteristics of a double-supermirror monochromator for neutron instrumentation at the Laboratoire Léon Brillouin are described. The aim of this monochromator is to reduce the intense γ radiation produced by conventional velocity selectors and to avoid a direct view of the guide while keeping a comparable neutron transmission (70%). The monochromator offers a continuous choice of wavelength selection in the range 0.5–2 nm.
