Description

The Frankfurt Van de Graaff accelerator can provide DC proton or alpha beam up to 10 μA. The terminal voltage is in the range of 1 to 2.5 MeV. Neutron production via Li-7(p,n) is possible and the local group has large experience with neutron-induced experiments. The necessary neutrons can be produced via bombarding thin, metallic lithium layers with protons of about 2 MeV. Under such conditions, neutrons with astrophysically interesting energies between 1 keV and 1 MeV are produced. In addition, a suite of He-3-neutron detectors is available. This detectors are very well suited to investigate astrophysically important neutron production reaction like C-13(alpha,n).

Services currently offered

The facility is currently not available to outside users. This might change in the future, as proposed within a Horizon 2020 infrastructure proposal.
