Neutron therapy is extremely effective method for cancer treatment because of the relatively bigger radiobiological effectiveness RBE compared with accelerated electrons and Gamma-rays effects on tissues. The geometry and material of the collimation system beside the neutron source are crucial elements for patient treatment with more sufficient absorbed dose rates with considering the other parameters. These reasons give valuable role for constructing and designing the assembly of collimator and source-collimator parameters in the most optimized way. Monte Carlo N-Particle Transport Code (MCNP) was used to optimize the geometrical design and materials of the collimator at the neutron therapy center of Tomsk Polytechnic University, which uses 13.6 MeV deuteron beam bombarded with thick beryllium target to produce fast neutrons used in tumor treatment. Carried out simulations indicated the possibilities of enhancing the flux of fast neutrons and the absorbed dose rate by a factor of 3 more. Also the results showed the ability of using narrow irradiation fields with comparable results with wide-aperture collimator designs by modifying the existed one. This leads to minimize the spending time for treatment and delivering more fast neutrons and dose rate to the treated tissues.
