6.3.3.2 Check of kβ-suppression
It is assumed that a ‘Spatial Calibration’ for your detector distance is performed and detector parame-
ters for ‘Full Discrimination’ as in Figure 6.22 are applied.
Instrument set up for scans to check the kβ-suppression:
Use settings from Table 6.1 according to your anode material.
2mm or 1° primary divergence
No kβ-Filter
2.5° primary and secondary Soller
Sample: NIST1976 (example) or another known sample
Adjust power not to exceed intensity in one strip over 5000cps
Perform a ‘Coupled TwoTheta/Theta’ scan from 31° to 36° (0.008deg/0.05s) covering the positions of
kα- and kβ-radiation reflections.
Switch to ‘Application’ and ‘Powder Diffraction’

1. Set the detector PSD angle to max. opening in degree in Config and remove any filters. Make
sure that trimmed detector parameters for High Gain, High Resolution and Veto=0.04V are
loaded.
2. Set Disc.Low to 0.120V and Disc.High to 0.320V in Tools and activate them.
3. Perform a Locked Coupled scan from 31 to 36° 2Th and save the file as LC_LL0d12-
UL0d32.brml.
