Abstract

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.

Data availability

During the RANC-2023 Conference the invited talk entitled “The experience with five years exploitation of digital germanium gamma spectrometers with muon sensitive veto shields” was presented. The current paper is devoted only to one part of this talk, focused on analysis of gamma spectra from coincidences of gammas and muons, so it is about the cases, which are during normal operation rejected. The other parts of the conference talk were based on published already papers.
