Energy deposition by neutrons below 20 MeV

There is a good agreement between energy deposition spectra simulated with G4SEE and measured with silicon diode detector at PTB PIAF and ENEA FNG facilities with 17 MeV, 14.8 MeV and 8 MeV neutrons.

Detailed scoring of neutron induced SEEs

Using G4SEE detailed scoring, 8 MeV monoenergetic neutron test run was simulated scoring the energy deposition of individual particles and analysed with G4SEE post-processing script. The energy deposition per particle have been summed up by the secondary particle product groups per event, clearly showing which inelastic or elastic nuclear reaction occurred event by event. The main contributors to total energy deposition distribution (grey) are the nuclear reactions producing Si-28 (blue), Al-28 (orange), Mg-25 (green) and Mg-26 (red). Contribution of events when no heavy nucleus, only proton and/or α particles were deposited energy is also shown on the plot (purple).
