“…The proton source that is modeled in the design of double layered BSA is protons having the energy of 30 MeV, resulted from a 30 MeV accelerator developed by the KURRI institute of Japan, i.e., C-BENS [7]. 30 MeV protons are exposed on 9 Be target to produce fast neutrons, subsequently processed by double layered BSA.…”

“…A part of the cyclotron that is yet to be developed is doublelayered BSA. The BSA is a system that transforms fast neutrons into epithermal neutrons and concurrently reduce contaminants accompanying the beams [9,10]. The design of BSA currently being used is in the form of double and multilayer configuration [2].…”

“…To have an optimal radiation beam from the BSA, optimization is required about configurations of components that constitute the BSA, in a graduated or step-by-step way [9,11]. However, graduated optimization most frequently does not yield radiation beams as required by the IAEA.…”

The genetic algorithm method is a new method used to obtain radiation beams that meet the IAEA requirements. This method is used in optimization of configurations and compositions of materials that compose double layered Beam Shaping Assembly (BSA). The double layered BSA is modeled as having two layers of material for each of the components, which are the moderator, reflector, collimator, and filter. Up to 21st generation, the optimization results in four (4) individuals having the capacity to generate the most optimum radiation beams. The best configuration, producing the most optimum radiation beams, is attained by using combinations of materials, that is by combining Al with either one of CaF2 and PbF2for moderator; combining Pb material with either Ni or Pb for reflector; combining Ni and either FeC or C for collimator, and FeC+LiF and Cd for fast and thermal neutron filter. The parameters of radiation resulted from the four configurations of double layer BSA adequately satisfy the standard of the IAEA.

Boron Neutron Capture Therapy (BNCT) is a therapy that utilizes the interaction of thermal neutrons with a boron-10 core that produces alpha particles and lithium nuclei. The result of this boron reaction has high linear energy transfer (LET). BNCT has an advantage over other radiation therapy in that it has a high selectivity level. This research was run using PHITS simulation to find out the value of neutron flux spread over a water phantom. The conclusion of the research is the distribution of neutron flux in the water phantom without boron is higher the the distribution of neutron flux in the water phantom containing boron

“…To overcome this weakness, double layer and even multilayer configurations have been developed. Such configurations are yet to be optimized, to obtain better radiation beams, and tested, to find if the characteristics of the resulting beams meet the requirements for BNCT (Monshizadeh et al 2015;Tanaka et al 2011;Kasesaz et al 2013).…”

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.
