Abstract
The use of a high-flux neutron source together with large curved one-dimensional position sensitive detectors (PSD’s) allows a complete powder diffraction pattem to be recorded simultaneously on a time scale of a few minutes or less so that transient phenomena such as chemical reactions in the solid state or first-order phase transitions can now be studied in real-time. Such measurements provide direct information on the progress of a reaction (kinetic law), but may also shed light on the transformations of structure and/or morphology which occur in the reactants during the course of a reaction. The instrumental parameters relevant to the design of time-dependent experiments are discussed. The applications are illustrated by four kinds of experiments: kinetic studies, thermodiffractometry, texture and stroboscopic measurements.
