Energy Resolution
Figure 3: Energy resolution with input count rate: The energy resolution of the analog system is dependent on the input count rate. The graph shows the dependency of the Full Width at Half Maximum with the incoming photons (input count rate) for different peaking times. Acquired with XIA Mercury.
