  • Title: Neutron production from 200-500 MeV proton interaction with spacecraft materials.
    Author: Maurer RH, Kinnison JD, Roth DR.
    Journal: Radiat Prot Dosimetry; 2005; 116(1-4 Pt 2):125-30. PubMed ID: 16604612.
    Abstract:
    We report on detailed energy spectra of neutron production > 14 MeV from collisions of 200-500 MeV protons with combinations of aluminium, graphite and polyethylene. Comparisons of normalised neutron spectra are made with respect to incident proton energy, angle of neutron production and material. In general, carbon (graphite) or polyethylene (by itself or in combination with aluminium) reduce secondary neutron production > 14 MeV relative to the production from interactions in aluminium.
