AB - Epithermal neutron source, based on vacuum insulation tandem accelerator and lithium target, has been developed and is now in use in the Budker Institute of Nuclear Physics. Neutrons are generated in 7Li(p, n)7Be reaction under proton energies from 2 to 2.5 MeV. A beam shaping assembly (BSA) for therapeutic neutron beam forming is used. It includes moderator, reflector, and absorber. In this work the simulation results of the depth dose rate distribution in modified Snyder head phantom for a range of neutron energies are presented and discussed. Variants of BSA optimization depending on tumor depth are proposed. The calculations were carried out by Monte-Carlo neutron and photon transport code NMC. Our research revealed that high quality neutron beam generation may be obtained with proton energy of 2.3 MeV. Discovered optimal schemes of BSA including sizes and materials are presented and discussed.
