Time evolution of rejected, coincidence spectra, registered on germanium gamma spectrometers with muon-sensitive veto shields

This paper presents the effects of background reduction with anticoincidence logical condition between the sum of muon-sensitive large scintillator veto detectors and a germanium detector as well as the time evolution of rejected, muon-induced coincidence gamma spectra. A special attention is paid to neutron effects. The digital event-by-event registration used for data acquisition opens possibilities to study in an off-line mode the variety of effects related to the time structure of all signals registered by detectors. In our laboratory currently we use two such systems with in-house written software Veto for off-line data analysis.
