Fragmentation of Ne ions with energy 400 MeV/u behind targets from different materials measured with PNTD

Abstract

This contribution describes the results of fragmentation of Ne ions with primary energy 400 MeV/u behind different shielding measured with plastic nuclear track detectors in the frame of experiments at HIMAC. The detectors were placed behind 6 different materials (PMMA, Teflon, graphite, Al, Fe, Cu) of various thicknesses, from the entrance up to the depths before the Bragg peak. Spectra of linear energy transfer were obtained for all materials and various thicknesses of the shielding used. Attenuation of primary Ne ions in various materials and the contribution of secondary particles and fragments to the total measured dose are presented.
