The design and operational principles are presented of a novel neutron diffractometer based on the flat‐cone technique which uses a 400‐cell one‐dimensional multidetector. Setting angles and measuring conditions are given for a generalized flat‐cone geometry. Test data were collected from an Ni(NH 3 ) 6 (NO 3 ) 2 crystal. They are compared with Bragg intensities measured from the same crystal with a conventional four‐circle diffractometer. A test for consistency between the two data sets gives R values of 0.019 and 0.031 depending on the weighting scheme. The results of independent structure refinements are in good agreement.
