This study investigates the use of a specially developed P-I-N diode to measure displacement damage in a silicon substrate caused by irradiation from 400 MeV/u 20Ne, 500 MeV/u 40Ar, 290 MeV/u 12C, and 6, 9, 12, 20 MeV electrons. Various energy levels of heavy ions attenuated by PMMA beam degraders were assessed. The study focuses on the forward voltage shift of the P-I-N diode as an indicator of displacement damage in silicon. Comparisons were made with simulated fluences, and the associated particle displacement Kinetic Energy Released per unit Mass (KERMA) to the silicon substrate. The inves...

Sustainable human exploration of the Moon will largely rely on in-situ resource utilisation, such as using regolith in habitat construction. This paper investigates the relative effectiveness of a polymer-enriched regolith brick versus a multilayer configuration of bare regolith and successive polyethylene layers as a passive shielding solution, when irradiated with Galactic Cosmic Ray (GCR) protons. Radiation–matter interactions are simulated with RayXpert® software and the dose equivalent in the ICRU sphere behind a representative habitat wall is calculated. The secondary emission of neut...
