The JHU Instrument Development Group in collaboration with NIST and the University of Maryland is developing a Doubly Focusing Neutron Monochromator to be used at NIST Center for neutron research. The Monochromator is the primary component of a neutron spectrometer (MACS), and will enhance the capabilities of current Crystallography and Material Science research. The Monochromator is composed of an array of 17 x 21 pyrolitic graphite crystals, capable of horizontally and vertically focusing neutrons at the Bragg wave length onto a sample.
