RESIDUAL NUCLIDES PRODUCED BY 290 MeV/u 12C IONS BEAM IN A LIQUID WATER TARGET

摘要

Nowadays, heavy ion beams are used in treatment of malignant tissues. The advantageous dose profile of ion beams is partly deteriorated by the nuclear interactions with tissue nuclei, leading for example to the fragmentation of the projectiles. The experimental information on these processes is scarce and for a limited group of ions. Therefore much relies on numerical simulation of the processes. It is the goal of the present study to provide exploratory calculations for the yield and fluence of nuclear fragments produced by ~(I2)C beams interacting with water target. This target is considered as first order approximation for the soft bio-tissues. For numerical simulations, a Monte Carlo approach coded in the FLUKA package has been selected.
