High power ion beam generator systems and methods
Provided herein are high energy ion beam generator systems and methods that provide low cost, high performance, robust, consistent, uniform, low gas consumption and high current/high-moderate voltage generation of neutrons and protons. Such systems and methods find use for the commercial-scale generation of neutrons and protons for a wide variety of research, medical, security, and industrial processes.
1. A neutron generator system comprising: a) an accelerator that produces an ion beam; b) a gas target positioned to be contacted by the ion beam; c) a target aperture separating said accelerator and said gas target; and d) a reverse gas jet, at said target aperture, that increases pressure differential across said aperture.
2. The system of claim 1 , wherein said reverse gas jet comprises a nozzle that diverges after it converges.
3. The system of claim 1 , wherein said reverse gas jet comprises a nozzle aperture of approximately ⅜ inch.
4. The system of claim 3 , wherein said reverse gas jet comprises a throat gap of less than 0.01 inch.
5. The system of claim 4 , wherein said reverse gas jet comprises a nozzle angle of 12.5 degrees.
6. A method of increasing a pressure differential across a target aperture of a neutron generator comprising employing a reverse gas jet at said target aperture, wherein said neutron generator comprises: i) an accelerator that produces an ion beam, ii) a gas target to be contacted by the ion beam, and said target aperture, and wherein said target aperture separates said accelerator and said gas target.
7. The method of claim 6 , wherein said reverse gas jet comprises a nozzle that diverges after it converges.
8. The method of claim 6 , wherein said reverse gas jet comprises a nozzle aperture of approximately ⅜ inch.
9. The method of claim 8 , wherein said reverse gas jet comprises a throat gap of less than 0.01 inch.
