We are proud to announce that our latest scientific work, “Validation of Proton Energy Loss in Regolith Simulants: PSI Proton Irradiation Facility (PIF) Beam Tests and MRADSIM Simulations,” has been published in Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms.
The study represents an important milestone in the experimental validation of MRADSIM, Beamide’s Monte Carlo simulation platform for radiation–matter interactions.
Bridging Simulations and Experimental Data
Reliable radiation simulations require rigorous experimental validation. In this work, we benchmarked MRADSIM against proton-beam measurements performed at the Paul Scherrer Institute (PSI) Proton Irradiation Facility (PIF), one of Europe’s leading facilities for proton irradiation experiments.
Using MGS-1 and JEZ-1 Martian regolith simulants, we investigated proton energy loss within representative planetary materials. Different Geant4 hadronic physics models were evaluated and compared with experimental measurements to identify the most accurate approach for reproducing proton transport through regolith.
Supporting Future Space Missions
Beyond the validation of MRADSIM, this research establishes a reliable benchmark methodology for future studies involving:
- Proton transport in planetary materials
- Radiation–matter interactions
- Martian regolith characterization
- Radiation shielding for space exploration
- Monte Carlo simulation validation
By strengthening confidence in simulation-based predictions, this work supports the development of more reliable radiation protection strategies for future lunar and Martian missions.
A Collaborative Scientific Effort
This publication is the result of an international collaboration involving Beamide and several research institutions. We sincerely thank all co-authors and partners for their valuable scientific contribution.
