Abstract

The Belgrade underground laboratory consists of two interconnected spaces, a ground level laboratory and a shallow underground one, at 25 m.w.e.. The laboratory hosts a low-background gamma spectroscopy system and cosmic-ray muon detectors. With recently adopted digital data acquisition system it is possible to study simultaneously independent operation of two detector systems, as well as processes induced by cosmic-ray muons in germanium spectrometers. Characteristics and potentials of present experimental setup, together with some preliminary results for the flux of fast neutrons and stopped muons are reported.
