Measurements of Charged-particle Production Cross-sections in Nuclear Reactions for Heavy-ion Radiation Therapy

Abstract

Heavy-ion radiotherapy using carbon ion beams of relativistic energies has raised high therapeutic outcomes against many tumors due to excellent physical properties and biological properties of carbon ions. Meanwhile, late effects are concerned because fragments such as α-particles, which are produced via carbon-ion induced nuclear reactions, impart doses to healthy tissues far away from the targeted tumor. For deeper understanding of the effect, knowledge about fragment productions is indispensable. In this article, we report experimental measurements of charged-particle production double-differential cross sections carried out by using heavy-ion beams from the accelerator HIMAC.
