摘要：

A detailed study of the NORDBALL Ge-BGO Compton suppression spectrometers has been performed. Special emphasis has been given to photoelectron yields of the scintillators, optimisation of charge integration in the electronics and the low energy thresholds of the BGO detectors. The time relation between the Ge detector and the BGO scintillator logic pulses has been studied in detail. Maximum Compton suppression factors of 12.0 and 12.7 have been measured for 60Co and 137Cs γ-rays respectively. Photon events observed between the full energy peak and the Compton edge suggest that other effects than multiple Compton scattering are involved. Such effects are usually not included in Monte Carlo simulations and could be the explanation of the factor of 2 deficiency between calculated and measured suppression ratios.
