Abstract

Beam-shaping assemblies have been designed to moderate high energy neutrons from the fusion reactions 2H(d,n)3He (DD) and 3H(d,n)4He (DT) for use in Boron Neutron Capture Therapy. The low yield of DD is an obstacle for the treatment of Glioblastoma Multiforme. Our analysis shows that the high-energy neutrons from DT can be moderated to epithermal energy range without reducing the neutron flux to a negligible level. With the optimal beam-shaping assembly design for DT, a 1A deuteron beam with energy of l20keV leads to a treatment time of 50 minutes. The dose near the center of the brain obtained with this configuration is about 50% higher than the dose from a typical spectrum produced by the Brookhaven Medical Research Reactor (BMRR), and is comparable to the dose obtained by other accelerator-produced neutron beams.
