BGO active shield for DEGASKošir, Gregor (Avtor) BGO detectorsgermanium spectrometersnuclear structureSiPManti-Compton shieldGSI/FAIRThe new DEspec Germanium Array Spectrometer (DEGAS), used at GSI/FAIR, includes bismuth germanate (BGO) scintillation detectors for active shielding to improve the sensitivity of its high-purity germanium (HPGe) detectors. The BGO detectors have a very high gamma-ray detection efficiency and can suppress background, such as Compton-scattered photons, by operating in an anti-coincidence veto mode with the germanium detectors. The BGO system was characterized and its performance was compared to simple gamma-ray propagation simulations.20242024-05-15 09:09:48Članek v reviji156233UDK: 539.1ISSN pri članku: 0168-9002DOI: 10.1016/j.nima.2024.169157COBISS_ID: 185996547sl
