Abstract
A grazing incidence monochromator has been constructed using the principle of differential reflectivity for order sorting. Some difficulties associated with earlier designs of this type have been solved and various refinements incorporated. The instrument includes a phase grating of the laminar type, as developed for use in the X-ray region. Details of the design and construction of the monochromator together with measurements of performance are reported, and a comparison with the calculated properties of the grating and optical system is made.
