An Electronic "Angle Marker" for the Siemens Texture Diffractometer
An electronic circuit is described which produces output pulses in response to preselected increments in specimen rotation on a Siemens Texture Diffractometer. The output pulses give an accurate indication of the specimen position, and may be used to trigger X-ray scaler read-out and reset operations for automatic data logging. The accuracy with which specimen position is determined is unaffected by variations in line frequency of the goniometer motor electrical supply, or by goniometer motor inertia when it is first switched on.
