ABSTRACT:
To permit X-ray analysis of crystals, selectively, with respect to both pession and rotation, without repositioning of the crystal and disturbance of crystal position, a goniometer head is located in the path of a primary X-ray beam and connected to a shaft which can be stepped in rotary movement by selective engagement through precision precession drive gearing. To prevent accidental engagement of the precession drive gearing, interlocks are provided to disable energization of the motor when rotation crystal diffraction tests are being made and the shaft is locked in position by a locking screw.
