The well-known, high-precision STOE STADI P two circle goniometer is the basis of STOE’s powder diffraction building block system (read more about ithere). Vertically or horizontally mounted, the STADI P can be built in Transmission/Debye-Scherrer or Bragg-Brentano geometry. Moreover, two STADI P goniometers, either in the same or different configurations, can be mounted in the same cabinet resulting in two completely independent instruments. However, the two goniometers can also share one source.
