Designing accelerator‐based epithermal neutron beams for boron neutron capture therapy

Abstract: The 7Li(p,n)7Be reaction has been investigated as an accelerator-driven neutron source for proton energies between 2.1 and 2.6 MeV. Epithermal neutron beams shaped by three moderator materials, Al/AlF3, 7LiF, and D2O, have been analyzed and their usefulness for boron neutron capture therapy (BNCT) treatments evaluated. Radiation transport through the moderator assembly has been simulated with the Monte Carlo N-particle code (MCNP). Fluence and dose distributions in a head phantom were calculated using BNCT tre… Show more

“…The sphere moderator model was chosen for investigating characteristics of different materials for creating epithermal neutron sources based on 7 Li(p,n) 7 Be reaction. In the center of the sphere was placed a source as a thin disk with a diameter of 4 cm, which is connected to the beam-line tube of the same diameter.…”
