Book excerpt: Drawing on the author’s practical work from the last 20 years, Techniques in High Pressure Neutron Scattering is one of the first books to gather recent methods that allow neutron scattering well beyond 10 GPa. The author shows how neutron scattering has to be adapted to the pressure range and type of measurement. Suitable for both newcomers and experienced high pressure scientists and engineers, the book describes various solutions spanning two to three orders of magnitude in pressure that have emerged in the past three decades. Many engineering concepts are illustrated through examples of real high pressure devices that have demonstrated their capacity and have produced scientific results. After introducing basic engineering concepts related to the elastic and plastic behavior of cylindrical pressure devices, the text emphasizes mechanical and neutronic properties of construction materials. Subsequent chapters describe numerous high pressure techniques, including liquid/gas, clamp, and McWhan cells. The book also focuses on Paris-Edinburgh devices, high pressure metrology, and scientific applications.
