Abstract
A rigid highly symmetrical rectangular frame (physical symmetry m m m) can carry two goniometer heads coaxially, but opposed apex to apex; t he frame itself is axially reversible. Used with monochromatized synch rotron radiation, it permits quick inversion of crystal orientations b y 180 degrees rotations about the diffraction vector, as is required f or comparison of lattice parameters in different parts of a single cry stal or between two separate crystals.
