Abstract: The results of the neutron beam shaping assembly (BSA) numerical modeling are shown in this work. The neutron generator is based on the ion source GISMO (Gasdynamic Ion Source for Multipurpose Operation) which was developed at IAP RAS. It is able to produce ion beams with total current of several hundreds of mA and at the energy of up to 100 keV. It is suitable for neutrons production from the D–D reaction. The optimization of the BSA geometric parameters was carried out. The neutron source is supposed to use for cellular cultures irradiation, which is made in the interest of the boron-neutron capture therapy development.

Keywords: Neutron generator, High-current gasdynamic ion source, neutrons, numerical modeling.
