Chemical Elements as Tracers of the Evolution of the Cosmos

Van de Graaff accelerator, Johann Wolfgang Goethe-Universität Frankfurt am Main (Frankfurt, Germany)


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.
