Short Pulse Neutron Generator
Agency / Branch:
DOD / USAF
A short-pulsed neutron generator is proposed for the detection of concealed high explosives. A recently developed RF-excited plasma neutron generator will be pulsed to produce the activating neutrons whose pulse length is 5-10 ns with a repetition rate of 100 kHz. Using the D-T nuclear reaction, we expect the proposed generator to produce an average yield of 10E9 n/s at this pulse length and rate. In Phase I an existing neutron generator will have a set of electrodes installed to chop the ion beam to produce the desired neutron-pulse time structure and a high peak yield. The present deuterium generator will be redesigned to support the safe use of tritium. The proposed system will be designed to be low cost, transportable, and mechanically and electronically robust, to ensure its wide useage. Unlike penning diode sources, the generator is expected to have a long lifetime. The project has a high probability of success based on the recent development by Adelphi Technology Inc. and Lawrence Berkeley National Laboratory of new RF plasma neutron generators.
