Small‐angle diffraction with a pulsed neutron source, using time‐of‐flight analysis to separate neutrons of different wavelengths, offers a very wide simultaneous Q range coupled to good Q resolution. Data reduction to allow for wavelength‐dependent effects may be achieved as a matter of routine. The cold neutron flux available from accelerator‐based neutron sources does not yet fully match that of the most intense reactor sources. Simulations show that the performance of proposed future instrumentation would be largely complementary to that of the best fixed‐wavelength instruments.
