Kappa Diffractometer
A Kappa geometry diffractometer is available in all three BioCARS stations: 14-BM-C, 14-BM-D and 14-ID-B.
The angular range of omega and kappa motions is limited by possible collisions with the collimator box, beam stop, detector and detector mount.
For detector distances over 100mm, it is safe to rotate omega between -90° and +90° when kappa is at 0° (usual data collection geometry). For shorter distances, inclined detector geometry or inclined kappa, please contact the BioCARS staff.
Samples can be mounted with horizontal spindle (omega=0°, kappa=0°) or inclined spindle (omega=0°, kappa=+60°). Fluorescence scans are done at omega=0° and kappa=-60°.
Phi rotation is used for centering of the sample and omega rotation for oscillation data collection.
Travel ranges are:
• X-axis: -5 to +5 mm
• Y-axis: -5 to +5 mm
• Z-axis: -12 to +12 mm
Pins (with loops or capillaries) or magnetic bases are mounted on a drill chuck. Two chuck sizes are available: the large one accommodates 1 to 5 mm pin diameters and the small one accommodates 1 to 3 mm diameters.
The Z-axis travel range accommodates 15-35 mm cryo loop pin lengths (measured from the magnetic base) when the small chuck is used and 25-35 mm pin lengths when the large chuck is used.
