The resolution function of a converging‐beam system for use in a small‐angle neutron diffractometer is investigated. It is shown that beam convergence in itself has only a small effect on resolution. Also a consideration is the monochromator and the correlation between wavelength and angle which it imposes upon the beam falling on the sample. Only minor modifications of existing monochromator and shield are required to produce a converging beam.
