The calibration will take several minutes. Result shall be at least ‘Satisfactory’. Especially for
long wavelengths or ‘High Count Rate’ modus it might be impossible to get ‘Satisfactory’. Even
in this case the energy resolution will be improved and can fulfill the specification.

6.3.3 Discriminator Setting and Kβ-Suppression
A correct setting of the ‘DAC Low’ and ‘DAC High Threshold’ together with a creful setting of the ‘DAC
Veto Threshold’ allows to suppress significantly fluorescence radiation (increasing the DAC Low value)
and kβ radiation (decreasing the DAC High value). The peak position for a given radiation is individual
for each detector. The following table shows the range, where one can expect the peak position for a
Discriminator Scan. Also listed are the energy resolution, remaining kβ part (NetInt(k

scans require’Calibration Application’.
