Neutron powder diffraction

An introduction is given to neutrons and their scattering from assemblies of atoms. This is linked with how neutrons may be exploited in the study of a variety of phenomena in the fields of crystallography, magnetism, solid-state reaction chemistry, engineering and materials science. Neutron-scattering instrumentation such as neutron sources, guides, collimators, choppers and monochromators, and detectors are described individually as well as how they are combined to make distinct diffractometers for high-resolution, high-intensity or specialized studies. Examples of data recorded on selected diffractometers are given and guidance is provided on the selection of diffractometer type, experimental arrangement and the ancillary equipment required for non-ambient studies.
