Abstract

This study particularly focuses on the dissipation processes of trapped ion beams such as deceleration and diffusion, which are caused by Coulomb binary collisions. It demonstrated that collisions in ions or low-temperature electrons have major influences on ion beams. Beam convergence was improved by applying a magnetic field. To assess the medical applicability of our neutron source, a combined Monte-Carlo simulation with Diffusion-Reaction model was employed to evaluate the available neutron yield for the Boron Neutron Capture Therapy (BNCT) neutron source under the beam diffusion conditions. The paper found that the proposed electrostatic trap of deuterium beam ions could provide sufficient neutron generation for the therapy.
