Neutron yield from protons interacting thick targets at 113 MeV and 256 MeV and carbon ions of 290 MeV/u interacting in water

Authors: B. Faddegon and J. Ramos-Méndez, University of California San Francisco, US

Short description: For protons, the Monte Carlo simulations consisted of a cylindrical target irradiated with a uniformly distributed, zero divergence, monoenergetic (113 MeV or 256 MeV) proton beam of radius equal to the radius of the target. For carbon ions, a monoenergetic carbon ion beam of 0.25 cm radius, 290 MeV/u energy and zero divergence was simulated. The target was a water phantom of 18 cm thickness.

Reference data: Experimental neutron yields from thick targets of different materials bombarded by protons of energies below 256 MeV were obtained from references [1][2]; for carbon ions interacting in water the data was obtained from reference [3].
