4.2 Detector Optics
Warning!
Voltage Danger - Bias voltages up to 500 V DC are accessible from the outside! They are
present on the metal sensor window on the front side of the detector! Never operate the
detector with Bias voltage switched on without having the detector optics mounted!
The optics of the detector consists of two major components, the Optics recognition block and the
alignment unit (see Figure 4.7):
The optics recognition block with two plug-in positions for e.g. Axial Soller slit, Kβ filter etc. All Sollers,
filters, slits and absorber have magnets which fix the slit in position when properly (two edges were
cut) inserted (see Figure 4.8). The plug-in modules can be inserted in one or the other position and are
recognized and displayed in DAVINCI if correct configured (see Figure 4.9).
Alignment possibilities (hidden behind a cover), normally do not need to be adjusted by the user.
Translation (ca. ± 2 mm, mind the backlash) allows to move the strips perpendicular to its length. This
changes the ‘Zero Offset’ value and allows to center a strip with respect to another optical slit in front
of the LYNXEYE XE.
Rotation (total range ca. 20 turns, loose the 2 fixing screws (1) by a 1/8 rotation) allows to align the
strips with respect to the slit focus. This movement is used to optimize spatial resolution (FWHM of
Bragg peaks) which requires a sample with well known sharp Bragg peaks.
