Fusion Based Neutron Sources for Security Applications: Neutron Techniques
The current reliance on X-Rays and intelligence for national 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 techn...
متن کاملResearch on fusion neutron sources
The use of fusion devices as powerful neutron sources has been discussed for decades. Whereas the successful route to a commercial fusion power reactor demands steady state stable operation combined with the high efficiency required to make electricity production economic, the alternative approach to advancing the use of fusion is free of many of complications connected with the requirements fo...
متن کاملFusion Based Neutron Sources for Security Applications: Energy Optimisation
There is a growing interest in the use of neutrons for national 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 neutron beam to be chosen to suit the application, rather than the application being chosen based on the available neutron beam energy. In this paper we discuss sim...
متن کاملDirect nuclear heating measurements in fusion neutron environment and analysis
Experimental measurement of nuclear heating rates has been carried out in a simulated D-T fusion neutron environment from 1989 through 1990 under the USDOE/JAERI collaborative program at the Fusion Neutronics Source Facility. The microcalorimetric technique has been employed for online measurements. Small probes of materials have been irradiated in close vicinity of a rotating target. A typical...
متن کاملNeutron Imaging at Spallation Neutron Sources
Neutron imaging is a powerful method for non-destructive investigations where the high penetration through metals and the high contrast for hydrogenous materials is exploited in particular. The complementary to X-ray studies is a clever alternative in many cases of scientific and industrial applications. Reactor based neutron sources are becoming less available, caused by the shutdown of aged f...
