Double-differential spectra generated by ions on tissue equivalent targets were calculated with the FLUKA code. Seven different species of ion beams were simulated, impinging onto an ICRU tissue equivalent target representing the chest of a patient under treatment. The following ion beams were investigated at an energy level capable of penetrating ICRU tissue up to a 26.2 cm depth: H, He, Li, B, C, N and O at 200.0, 202.0, 234.3, 329.5, 390.7, 430.5 and 468.0 MeV u–1, respectively. The double-differential spectra of secondary neutrons, protons, photons, positive and negative pions, electrons and positrons were scored over the entire solid angle. Curve-fitting of the calculated data is also given.
