Our group had designed Beam Shaping Assembly (BSA) for Accelerator-based BNCT. This system radiates collimated neutron beam from a hole at the exit of BSA. There had been no nozzle at the BSA, and it will cause some difficulty when it works in real situation. In this study, we designed the nozzle of neutron beam and evaluated the beam quality whether it reaches a certain level by means of Monte Carlo Simulation.
