Development of a Neutron Radiography System based on a ۱۰ MeV Electron Linac

A thermal neutron radiography unit using the neutrons which emits a ۱۰ MeV electron linac compact has been designed and simulated via MCNPX Monte Carlo code. The facility was carried out for an extensive range of values for the collimator ratio L/D, the main parameter which describes the quality of the produced radiographic images. The results show that the presented facility provides high thermal neutron flux; while with the use of single sapphire filter fulfills all the suggested values which characterize a high quality thermal neutron radiography system. A comparison with other similar facilities indicates that the use of a photoneutron source using a ۱۰ MeV electrons beam is a useful substitutional for radiographic purposes.
