Abstract
Monte Carlo simulations, using Geant4, were performed for 4He, 12C, 28Si and 56Fe ions at energies of 300, 900 and 2400Â MeV/n incident upon aluminum shields having areal densities of 5.4, 13.5, and 54Â g/cm2. The identity, energy and spatial distribution of all particles downstream from the shielding were analyzed using a novel approach based on proximity distributions. Results indicated that pixel dimensions on the order of 1Â mm were sufficient to reduce errors caused by coincident events for active space radiation detectors.
