A detailed knowledge of the light ions interaction processes with matter is of great interest in basic and applied physics. As an example, particle therapy and space radioprotection require highly accurate fragmentation cross-section measurements to develop shielding materials and estimate acute and late health risks for manned missions in space and for treatment planning in particle therapy. The Fragmentation of Ions Relevant for Space and Therapy experiment at the Helmholtz Center for Heavy Ion research (GSI) was designed and built by an international collaboration from France, Germany, Italy, and Spain for studying the collisions of a 12 C ion beam with thin targets. The collaboration's main purpose is to provide the double-differential cross-section measurement of carbon-ion fragmentation at energies that are relevant for both tumor therapy and space radiation protection applications. Fragmentation cross sections of light ions impinging on a wide range of thin targets are also essential to validate the nuclear models implemented in MC simulations that, in such an energy range, fail to reproduce the data with the required accuracy.

Abstract. Nuclear fragmentation reactions induced by alpha particle projectiles are an important component of the space radiation problem. Inclusive isotopic spectral distributions and double differential cross sections are used as input to the Boltzmann transport equation, which is often solved in many space radiation applications. For alpha particle projectiles, it is found that most of the available experimental data are below the pion threshold. This is a significant validation gap because the important energy range for galactic cosmic rays extends up to 10 GeV/n and above.
