Figure 2
Left: degrees of freedom (DOF) of the D3 diffractometer. The translations GMX, STY and STZ and the rotation ω are used for scanning operations, i.e. with the X-ray shutter opened, the translations GMY and GMZ are used for sample positioning during alignment only. The active X-ray beam feedback to an X-ray beam-position monitor in the so-called exposure box (X-Box) allows the positioning of the beam via the EBX and EBY translations. The on-axis microscope is the reference device to which all others are aligned; the sole DOF with a relation to the microscope is the GMZ translation of the goniometer that is used to bring the sample into focus. Right: DOF mapped onto the actual goniometer.
