Abstract: The expected performance of single-crystal time-of-flight diffraction at a potential long pulse spallation source is discussed for both small and large-unit-cell structures. The requirements and capabilities in biomacromolecular structure analysis at high, atomic resolution are focused on. Data collection times are predicted on the basis of a detailed evaluation of the counting-statistical quality of a complete data set. It is found that a long pulse source would excel the capabilities at the best existing steady state source. Most promising for advances in the more challenging structural problems, however, looks a short pulse spallation source with an intermediate-temperature coupled moderator.
