Abstract
Nuclear fragmentation complicates both spacecraft shielding design and treatment planning for radiotherapy. Hadron therapy treatments require very high precision on the dose deposition (±2.5% and ±1.1mm) in order to keep the benefit of the precise ion’s ballistic. The largest uncertainty on the physical dose deposition is due to ion’s nuclear interaction through the traversed material. The nuclear interactions of the incident ions must also be taken into account in understanding and addressing the effects of galactic cosmic rays ions on humans and sensitive components in space. Today the simulation codes are not able to reproduce the fragmentation process with the required precision. In order to constraint the model within the codes and complete fragmentation cross section databases, experimental campaign has started since few years at LNS in Catania to study the fragmentation of 12C on various target at intermediate energies. Measurements of energy and angular distributions of charged fragments, and double differential cross sections will be addressed. Preliminary results and future perspectives are reported.
