Fusion Based Neutron Sources for Security Applications: Energy Optimisation

There is a growing interest in the use of neutrons for na- tional security. The majority of work on security focuses on the use of either sealed tube DT fusors or fission sources, e.g. Cf-252. Fusion reactions enable the energy of the neu- tron beam to be chosen to suit the application, rather than the application being chosen based on the available neu- tron beam energy. In this paper we discuss simulations of fusion reactions demonstrating the broad range of energies available and methods for adapting the neutron beam en- ergy produced by target/projectile combinations.
