Long-Life Electrical Neutron Generator

40067 November 4, 1996 First Point Scientific Advanced neutron-based sensors are required in support of treaties to enforce international non-proliferation and national security goals pertaining to weapons of mass destruction. Reliable, long-life sources of high energy neutrons are critically needed for use in these sensor systems. This project will develop a new type of solid-target, sealed neutron generator to meet the requirements for high neutron output (up to 1011 n/s at 14 MeV), low power consumption (3000 hours). Furthermore, the generator system, which can be battery operated and automatically controlled, will be portable, and it can be operated dc or pulsed. The generator concept will be demonstrated and optimized for two applications: (1) detection of chemical agents and explosives and (2) detection of nuclear material in large containers. Phase I will: (1) construct a proof-of-principle generator for operation at a 2.5 MeV neutron flux of 107 n/s; (2) experimentally demonstrate the predicted generator operating characteristics; and (3) develop the conceptual designs for two full-scale laboratory prototype generator systems, one for each application. In Phase II, these advanced neutron generator systems will be developed and demonstrated. Anticipated Results/Potential Commercial Applications as described by the awardee: Applications should include: (1) detection of explosives and chemical warfare agents; (2) detection of small quantities of nuclear material in 200-liter drums; (3) measurement of the nuclear material content in nuclear fuel components and nuclear waste; and (4) detection of land mines.
