Abstract
In accordance with the present invention at least two different grades of HOPG material with different d-spacings are combined to form a composite HOPG monochromator with increased spacing spread (.DELTA.d/d) defined by the combination of the two HOPG materials with each HOPG material oriented relative to one another so that their layer planes are parallel. The increased .DELTA.d/d should yield higher neutron beam intensities in certain types of backscattering instruments.
