Physical and Chemical characterization of Galactic Cosmic Rays Fragmentation – CLINM

Light charged particles and neutrons produced during interaction of galactic cosmic rays (GCR) in shielding materials can lead to significant dose to astronauts during a space flight. In this context, Monte Carlo (MC) simulations are often used to estimate the radiation fields to which astronauts would be exposed during long-term missions in space. The calculations performed in these codes are based on models which are not always in agreement with data. Therefore, measurements of charged particles and neutrons produced by GCR interaction with shielding targets are needed to improve these hadronic models. The CLINM project aims at, on one hand, measuring the characteristics of these particles (charge, energy) with a time-of-flight detection system (for charged particles and gamma-rays) and a recoil proton telescope (for neutrons). On the other hand, the impact of these GCR on biomolecules composing living cells will also be measured. The resulting data should then be implemented in open-sources Monte Carlo codes, and will also be made available to the scientific community via the EXFOR database..
