The use of electron linac for high quality thermal neutron radiography unit

A Thermal neutron radiography facility based on photoneutrons which produced by an electron linac was studied with the final goal to suggest an attractive alternative to the nuclear research reactors neutron sources which are used for radiographic purposes. The design and the optimization of the facility have been simulated using the MCNPX Monte Carlo code. The relevant with thermal neutron radiography parameters such as the thermal neutron flux, the L/D ratio and the thermal neutron content calculated for an extensive range of values. The results specify that the proposed facility meets all the required values for quality thermal neutron radiographies. The overall evaluation of the unit was also realized through the comparison between the studied facility and some published works.
