Overview of the Current (Alpha,Neutron) Campaign Capabilities

Alpha-induced neutron production is a source of neutrons in both stellar and nuclear energy settings, as well as serving as a mirror to (n, a) reactions. In addition, (a,n) reactions on light nuclei are sources of background for ton-scale detection systems, as well as in non-destructive assay measurements of nuclear material. A new nuclear data collection campaign has been started at the University of Notre Dame's Nuclear Science Laboratory to detect multiple channel types in (a,n) reaction systems. The campaign currently employs 11 liquid-scintillator neutron detectors, three HPGe gamma-ray detectors, and 28 silicon photodiode charged particle detectors. This multi-type detection allows for a holistic measurement of the reactions being studied. In addition, with multiple detector types all measuring the same reaction, with different systematic biases, cross-verification can be done. An experiment has already been performed on the 10B(a,n) reaction, as well as initial measurements of the 11B(a,n) reaction. An overview of the current capabilities of the experimental campaign will be presented.
