Angle calculations are derived for the operation of a `4S+2D' six‐circle X‐ray or neutron diffractometer. The six degrees of freedom [four sample‐orienting (`4S') and two detector‐orienting (`2D')] of the diffractometer are used to control the scattering vector and a reference vector in the laboratory frame of reference. Several modes of operation unavailable in other types of diffractometer are presented.
