Epithermal Neutron Beam Generator Design for Bnct

BNCT is a radiotherapy modality based on the neutron capture and fission reactions that occur when boron-10 is irradiated by thermal neutrons. This reaction generates alpha and lithium that produce high density of ionizations in close to the reaction site. The concept provides high absorbed doses into the cancerous cells preserving the adjacent healthy tissues. Nowadays, the available neutron sources for BCNT are large research reactor facilities, which represent a highly complex and expensive technology involving large dimension and radiological concerns due to radiation protection. The present paper describes accelerator-based epithermal neutron source in order to overcome limitations of reactor technology in BNCT. The main goal is to design the mechanical structure and simulate the electromagnetic behavior of the device. The methodology consist in apply the AutoCAD Mechanical package in the design and CST package for electromagnetic evaluations. As conclusion, the device provides a neutron flux capable of sustaining boron fission reaction in suitable levels for generating effective and selective therapeutic doses at the brain.
