Secondary particle yields from 400 MeV/u carbon ion and 250 MeV proton beams incident on thick targets

The double differential particle yield produced by hadron beams striking thick targets of copper, tungsten and ICRU tissue have been determined by means of the Monte Carlo transport code FLUKA (version FLUKA 2008.3b.1). 400 MeV/u carbon ions and 250 MeV proton pencil beams have been considered. Secondary neutrons, photons and protons have been scored. In order to validate the obtained data, a few simulations have been also repeated with MCNPX 2.6.0. The calculated results are presented and compared with the experimental data reported in literature. They should be very useful to solve a number of problems related to technological aspects of hadrontherapy.
