Throughput
Figure 2: The diagram provides the throughput behavior of the AXAS-M H80 CUBE including the optional Digital Pulse Processor (DPP2). It shows the dependency of the output count rate with the input count rate for different peaking times. The lower the peaking time, the higher is the maximum throughput for a system.
Energy Resolution
Figure 3: Energy Resolution with Input Count Rate: The energy resolution of the AXAS-M H80 CUBE acquired with KETEK DPP2: The energy resolution of the digital system is absolutely independent from 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.
