Figure 6.23: Discriminator scan for Cu radiation without Ni-filter.
Depending on your application (e.g. GM mirror or kα1 monochromator) it may also useful to use one of
the following discriminator settings (example for this detector), which increases the intensity by a few
percent:
DAC Low/High Threshold should be set to 0.208V and 0.3V for fluorescence suppression (requires kβ-
filter)
DAC Low/High Threshold should be set to 0.120V and 0.232V for kβ-discrimination.
DAC Low/High Threshold should be set to 0.120V and 0.500V and DAC Veto Threshold. to 0.5V for
max. count rates (No fluorescence suppression, requires kβ-filter).
