User Manual LYNXEYE XE Detector

6.6.3 Aligning the Diffractometer
Note
Save the Configuration and the State file from the CONFIGURATION and DETECTOR
plugin. It is recommended to start the alignment of the diffractometer with the default values
set for the LYNXEYE XE detector in the CONFIGURATION.
The procedure might destroy any previously performed calibrations (when using the default configura-
tions and should be the 1
st
step setting up a diffractometer.
The 0D functionality allows to align the diffractometer without a scintillation counter and without the
additional secondary optics. The detector must be mounted in 0° position. It is highly recommended to
download the default settings for the given detector distance to center the middle strip with respect to
the detector arm. This allows later to use the maximum number of strips.
To minimize dead time effects, you should load one of the default configurations LYNX-
EYE_XE_Diff_Align_Cu_Cr_Co_Fe_Tube.bfscn or LYNXEYE_XE_Diff_Align_Mo_Ag_Tube.bfscn or
the state file for ‘High Count Rate‘ of your detector, you should reduce the count rate by absorbers to
maximum 100 kcps/strip.
In case you want to use your actual High (energy) Resolution Configuration, you should reduce the
count rate by absorbers to maximum 10 kcps/strip.
For Tube Scans the opening of the LYNXEYE XE should be set to 10mm.
For Detector Scans the opening of the LYNXEYE XE should be set to 0.075mm.
Under these conditions, the ZI values for the Tube and Detector can be determined.
6.6.4 Setting the diffractometer to Default Values
1. Open the ‘DETECTOR’ plugin
2. Load the state file for ‘High Count Rate‘ of your detector or one of the default configurations
LYNXEYE_XE_Diff_Align_Cu_Cr_Co_Fe_Tube.bfscn or LYNXEYE_XE_Diff_Align_
Mo_Ag_Tube.bfscn
3. Insert sufficient absorber and perform a download in case of Configuration files.
