Fusion Based Neutron Sources for Security Applications: Neutron Techniques

The current reliance on X-Rays and intelligence for na- tional security is insufficient to combat the current risks of smuggling and terrorism seen on an international level. There are a range of neutron based security techniques which have the potential to dramatically improve national security. Neutron techniques can be broadly grouped into neutron in/neutron out and neutron in/photon out tech- niques. The use of accelerator based fusion devices will potentially enable to wide spread application of neutron se- curity techniques due to the potential for much safer oper- ation than that offered by fission or sealed tube sources. In this paper we discuss some of the neutron security tech- niques available and the advantages they present.
