Efficient data coverage using a kappa goniometer

AppNote SMX009: Single crystal X-ray diffractometer with kappa goniometer for efficient data collection

Background

Four-circle kappa goniometers have been central to single crystal diffractometers since their inception and remain a popular choice for scientists who require the combined flexibility and precision to collect efficient and accurate data. Rigaku Oxford Diffraction recently launched the XtaLAB Synergy systems, which amongst many improvements, includes an updated goniometer. The goniometer incorporates the following features: new motors allowing it to move twice as fast as its predecessor and with very high accuracy, a symmetrical theta range for flexibility in gathering data in reciprocal space, a new beamstop holder design to allow the detector to be positioned nearer to the sample and a telescoping theta arm for long detector distances.
