Sammanfattning

A bismuth-germanate (BGO) anti-Compton shield (ACS) for Compex germanium detector modules was designed, built, and characterised. BGO performance was evaluated for light output and energy resolution. The response of the ACS shield and its impact on germanium detector spectra was measured for standard ⁶⁰Co, ¹³³Ba, and ¹³⁷Cs sources. The results were compared to comprehensive Geant4 simulations. The ~70% improvement of the peak-to-total ratio for the ¹³⁷Cs 662-keV γ-ray peak is in good agreement with expectations from the simulations. A ¹³³Ba source exemplifies decay schemes of odd-A superheavy nuclei. Congruence between measured and simulated spectra indicates that the Compex plus ACS multi-detector module is well understood.
