Science highlights from the shallow underground laboratory Felsenkeller Dresden — •Konrad Schmidt and Daniel Bemmerer — Helmholtz-Zentrum Dresden-Rossendorf

Underground accelerator laboratories are important instruments to measure nuclear reactions with low cross sections in experimental nuclear astrophysics. The reduced detector background due the shielding from cosmic rays allows the study of astronuclear reactions at energies relevant to Big Bang nucleosynthesis and stellar burning. The reactions 3He(a,g)7Be and 12C(p,g)13N have recently been studied at the shallow underground laboratory Felsenkeller Dresden, where a 5 MV accelerator provides several high intensity ion beams and an ultra-low background counting setup for activation measurements. In the talk, the latest scientific results from the Felsenkeller laboratory, its current capabilities and upcoming enhancements will be summarized.
