Prokhorets S. Models and methods for design of the neutronography facility

This thesis is devoted to the actual task of design of the complex physical and technological facilities where nuclear radiation is used. In this work it is studied the system of the complex technical devices, which are used for obtaining, transport and forming of the neutron beams with specified energy range, for obtaining and visualization of the neutronographic images. Considered formalization of the processes of the neutron interaction with the matter was used as simulation model for creation of the specialized and universal program complexes. Formalization methods of the electrophysical parameters of the neutronographic image position sensitive detector were considered and criterion functional and set of constraints for controlled parameters occurring while its design was defined. Neutron fluxes at the output of the forming system were estimated.
