SBIR Phase I: Distributed Neutron Generator

点击翻译按钮获取中文摘要

*** 9660132 Bayless This Small Business Innovation Research Phase I project addresses the critical need for long-life neutron generators for use in nondestructive evaluation and in situ testing. A new type of solid-target, sealed neutron generator, the Distributed Neutron Generator (DNG), is the focus of this research. It will be designed to meet requirements for high neutron output (up to 103 n/s at 14 MeV), low power consumption (1 kW), small size, low cost, and long lifetime (3,000 hours), and can be operated dc or pulsed. No existing neutron generator offers this combination of desirable characteristics. The overall objective of the project (Phases I and II) is to demonstrate the feasibility of the DNG concept. The objectives of Phase I are to: (1) construct a proof-of-principle generator for operation at 125 kV; (2) to experimentally demonstrate that a uniform, high energy ion beam can be generated; and (3) to develop the conceptual design for a Phase II laboratory prototype DNG system. A large company, which is interested in future commercialization of DNG technology, will participate in Phase I. If successful, the project will develop a new type of neutron generator with highly advanced capabilities. Discussions with potential users indicate that the market for this generator will be large. Its applications include: (1) ore analysis; (2) airport luggage inspection; (3) detection of landmines, explosives, chemical warfare agents and small quantities of nuclear material; (4) industrial process control; and (5) instruments for treaty verification. ***
