Abstract

The measurements performed using a fully stripped carbon ions beam of 80MeV/u impinging on a Poly-methyl methacrylate (PMMA) phantom at the Laboratori Nazionali del Sud (LNS) dell´INFN in Catania, Italy, are shown. The study of the neutral particles production from the fragmentation of the Carbon Projectiles plays a crucial role in the present development and delivery of therapeutical beams for hadron therapy. Measurements performed monitoring PMMA phantoms are fundamental to validate MC simulations and confirm expected performances of detectors used for monitoring purposes. The feasibility of online dose monitoring has been investigated using LYSO detectors for prompt photons and NaI crystals for β⁺ decays.
