LYNXEYE XE Detector User Manual
DOC-M88-EXX240 V1 – 03.2014 6-35
6.6 0D-Mode
In 0D-mode a variable block of strips can be defined by software. All events collected by these strips
are counted as one single rate at a specific angular position – similar to a scintillation counter. The
most benefit can be achieved with the aid of a special detector holder (0/90° mount) by using the 90°
rotated position (around the diffracted beam) in combination with a standard 0-dimensional optics. In
this case, the line intensity is distributed to up to 192 strips of 75 µm width which results in detectable
count rates of some 100 kcps, depending on the detector mode. This will give the option to measure
some 10 million cps. Even if in most cases not needed, the LYNXEYE XE in 0-D Mode can be com-
bined with the Automatic or Rotary Absorber in Auto Mode.
Continuous and Step Scans are supported for all motors configured in combination with up to 3 Axes
Indexer Boards. This mode is most useful for aligning the diffractometer drives.

ARD
6.6.2 Standard operation
0-D Mode does not require a special setting for the LYNXEYE XE in the configuration of the diffrac-
tometer. When selecting the Details button in the DIFFRAC.COMMANDER two buttons are available
for the PSD under Scanning Mode (see Figure 6.32.
The default mode is ‘1D’. After clicking the 0D button a value for Opening has to be defined, (see Figu-
re 6.32). The smallest possible value is 0.075 mm, corresponding to one strip. Odd multiples of 0.075
mm can be selected up to a complete opening of approximately 14 mm.
All available Scan types are shown in (see Figure 6.33). Step and Continuous scan are possible (see
Figure 6.34). More or other scan types might be displayed according to your diffractometer setup.
The same features are available in the DIFFRAC.WIZARD (DOC-M88-EXX194).
