“…The resulting neutrons from the cyclotron are regulated so as to comply with the requirement set by the International Atomic Energy Agency (IAEA). Based on these criteria, the minimum beam intensity of the epithermal neutrons (1 eV < E < 10 keV) should be 5 × 10 8 n∕cm 2 .s, the number for fast neutron (E > 10 keV) dose rate per epithermal neutrons flux and gamma dose rate per epithermal neutron flux should be less than 2 × 10 −13 Gy cm 2 and the minimum number for the ratio of the epithermal neutrons flux to the thermal neutrons (E < 1 eV) flux should be 100 (Ganjeh and Eslami-Kalantari 2019). The part of the cyclotron that is capable of processing the neutron beam is a beam shaping assembly (BSA).…”

A Double Layer Beam Shaping Assembly (DLBSA) was designed to produce epithermal neutrons for BNCT purposes. The Monte Carlo N-Particle eXtended program was used as the software to design the DLBSA and phantom. Distribution of epithermal neutron and gamma flux in the DLBSA and phantom and absorbed dose in the phantom were computed using the Particle and Heavy Ion Transport code System program. Testing results of epithermal neutron beam irradiation of the water phantom showed that epithermal neutrons were thermalized and penetrated the phantom up to a depth of 12 cm. The maximum value of the absorbed dose was 2 × 10-3 Gy at a depth of 2 cm in the phantom.
