For the measurement of reactions with small cross sections as aimed for in the Laboratory for Underground Nuclear Astrophysics (LUNA) at the Gran Sasso National Laboratory (LNGS), low detector background levels are compulsory. Background measurements with a BGO detector used at LUNA have been evaluated to develop a model of the contributions in the region of interest for ongoing and planned measurements. Conclusions from this model and implications for further background reduction for this detector setup are discussed. A customized lead shielding against environmental backgrounds is described.

Abstract
For the measurement of reactions with small cross sections as aimed for in the Laboratory for Underground Nuclear Astrophysics (LUNA) at the Gran Sasso National Laboratory (LNGS), low detector background levels are compulsory. Background measurements with a BGO detector used at LUNA have been evaluated to develop a model of the contributions in the region of interest for ongoing and planned measurements. Conclusions from this model and implications for further background reduction for this detector setup are discussed. A customized lead shielding against environmental backgrounds is described.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
