Abstract
The power of the state-of-the-art neutron powder diffractometer suite at the Institut Laue-Langevin for investigating the structure of nondeuterated materials is presented using gypsum, CaSO<sub>4</sub>·2H<sub>2</sub>O, as a reference material. It is shown that flexible modern neutron powder diffraction instruments at reactor-based sources can yield data with sufficient counting statistics above the incoherent scattering contribution to perform unconstrained refinements in relatively short time periods (from minutes to a few hours, depending on the sample size and the instrument choice), without the requirement for significant changes to the standard operational modes of the instruments. The results are critically compared with previous literature from single-crystal and powder X-ray and neutron measurements on deuterated and nondeuterated gypsum.
