文摘

In this study, a beam shaping assembly with high epithermal neutron flux output was designed based on a D–T neutron generator using Monte Carlo N-particle Transport Code. D₂O-54Fe and AlF₃-60Ni interlayer moderator, efficient multiplier, filters, and reflector were used to improve the neutron beam quality according to the requirements of boron neutron capture therapy while maintaining high flux of epithermal neutron beam. In addition, the dose performance of the beam from our proposed facility was assessed in the Snyder head phantom. The simulation results proved that the proposed neutron beam was applicable to the treatment of deep-seated brain tumor.
