Characterization of the cesium sputter ion source for the new Felsenkeller 5 MV underground accelerator — •Felix Ludwig^1,2, Martina Koppitz^1,2, Daniel Bemmerer¹, and Kai Zuber² — ¹Helmholtz-Zentrum Dresden-Rossendorf (HZDR), Dresden — ²Technische Universität Dresden

In order to determine the cross section of the ¹²C(α,γ)¹⁶O reaction at astrophysically relevant energies, an accelerator with a stable and intensive ¹²C ion beam in an ultra low background environment is needed. For this purpose a 134-MC-SNICS cesium sputter ion source is going to be part of the Felsenkeller shallow underground accelerator facility. To determine the characteristics of this ion source overground tests were undertaken at HZDR. The contribution will report on long time measurements of the ion current and the beam emittance.
