Monte Carlo simulation tool for the 7Li(p,n) reaction — •Rene Reifarth1,2, Michael Heil1, Franz Käppeler3, and Ralf Plag1,2 — 1GSI, Darmstadt, Germany — 2Goethe Universität Frankfurt, Germany — 3FZK, Karlsruhe, Germany
The 7Li(p,n) reaction in combination with a 3.75 MeV Van-de-Graaff accelerator was routinely used at FZK to perform activation as well as time-of-flight measurements with neutrons in the keV-region. Planned new setups with much higher proton currents like SARAF and FRANZ and the availability of liquid-lithium target technology will trigger a renaissance of this method. A detailed understanding of the neutron spectrum is not only important during the planning phase of an experiment, but also during the analysis of activation experiments.
Therefore a Monte-Carlo based program was developed, which allows the simulation of neutron spectra considering the geometry of the setup and the proton energy distribution. The program was developed and tested while accompanying a number of recent activation experiments at FZK. A comparison with measured data, examples of past usages, and potential future applications will be presented.
