A multiple-crystal data-collection method in time-of-flight neutron Laue diffraction

A novel multiple-crystal data-collection method has been employed to obtain neutron diffraction data simultaneously from several randomly oriented crystals of a low-symmetry molecular material. The method exploits the ability of time-of-flight neutron Laue diffraction to resolve the overlapping diffraction patterns from the multiple-crystal sample. The method has been applied to acetylcholine bromide, yielding a good-quality structure refinement. This opens up a possibility for wider exploitation of the method in collecting data sets more rapidly, under more extreme sample environment conditions and from smaller single-crystal samples.
