THE NRL AUTOMATIC, SINGLE-CRYSTAL, NEUTRON DIFFRACTOMETER,
Abstract
An automatic diffractometer for the study of the physics of crystalline solids by means of neutron diffraction has been completed at the NRL Nuclear Reactor Facility. It was designed for maximum versatility in studying the structure of materials, with special emphasis on magnetism, but also with an emphasis on metallurgical and structural chemical problems. On the basis of the initial experiments it appears that useful diffraction data is possible from crystals as small as 1 cubic millimeter, although 10 cubic millimeters is probably a more suitable size. Automatic programming brings the specimen crystal into the position for reflection and rotates the crystal and counter through the Bragg angle by independent adjustments, each of which is provided with an electrical readout to a digital recorder. A computer program does all preliminary processing of data tapes. (Author)
