The document describes a new diffractometer arrangement that combines the openness of a kappa goniometer configuration with an additional degree of freedom for detector movement. Specifically: 1) The detector will attach to a two-degree-of-freedom circle mounted on the vertical axis of an Enraf Nonius kappa goniometer, creating a (3s+2d) diffractometer. 2) This will allow the detector to rotate about the vertical axis as well as a horizontal axis, facilitating detection of out-of-plane scattering vectors. 3) The original servomotors are being replaced with stepper motors and gear trains for more precise sample placement and detection while reducing backlash
