【 摘 要 】

The goal of this demonstration was to show that it is possible to generate electronic signals that can accurately mimic the signals that are produced by a high-purity germanium (HPGe) gamma-ray detector. As an example of this fidelity, we decided to show that it was possible to perform a complex, multiplet-resolution analysis of a portion of the spectrum acquired from the gamma-ray spectrum synthesizer. We further showed that the results of this analysis were consistent with what would be obtained from a spectrum acquired from a real plutonium source and a real HPGe detector. The gamma-ray synthesizer used in the JRC Ispra demonstration was our first laboratory prototype. In this version of the synthesizer we produced signals that mimicked the output of an HPGe detector preamplifier. Although not shown at Ispra, we have also demonstrated that we can produce signals that mimic the signals produced in the detector itself.
