Abstract The fragmentation cross sections of carbon ion beams with kinetic energies of 115– 353~MeV/u 353 MeV / u impinging on thin targets of graphite (C), polyvinyl-toluene (C ₉ 9 H ₁₀ 10) and PMMA (C ₅ 5 O ₂ 2 H ₈ 8) have been measured at 90 ^ ∘ and 60 ^ ∘ at the CNAO particle therapy center (Pavia, Italy). Two detection arms were positioned at two different angles to perform the measurement at 90 ^ ∘ and 60 ^ ∘. The fragment species have been identified in charge (Z ₈₃ id = H) and mass (M ₈₃ id = ¹ 1 H, ² 2 H, ³ 3 H) combining the information of the deposited energy in thin plastic scintillators, of the deposited energy in a thick LYSO crystal and of the fragments Time of Flight (ToF) measurement. The ToF was also used to compute the fragments measured
