Section: claims

1. An accelerator neutron source (ANS), the ANS comprising:a cylindrical housing comprising a cavity containing a gas comprising deuterium and tritium;a field ionization (FI array) within the cavity and configured to generate deuterium and tritium ions from the gas;a target comprising implanted ions within the cavity, the target configured to receive the deuterium and tritium ions and generate neutrons; anda cylindrical grid accelerating electrode within the cavity, the accelerating electrode coaxial with the housing and configured to direct the deuterium and tritium ions to a central region of the cavity within the cylinder of the accelerating electrode and aligned with a central axis of the housing and the accelerating electrode and to eject the ions along the central axis toward the target. 2. The ANS of claim 1, wherein the FI array further comprises plurality of nanotips positioned about a substrate, the nanotips extending from an inner surface of the housing into the cavity. 3. The ANS of claim 2, wherein the nanotips of the FI array are positioned cylindrically about the inner surface of the housing. 4. The ANS of claim 1, wherein the FI array, the accelerating electrode, and the target are operably connected and configured to produce about 10{circumflex over ( )}9 neutrons per second. 5. The ANS of claim 1, wherein the FI array further comprises an ionization voltage source configured to apply a voltage to the electrodes of the FI array. 6. The ANS of claim 1, further comprising an extraction ring configured to extract deuterium and tritium ions from the central region of the cavity within the cylinder of the accelerating electrode. 7. The ANS of claim 1, further comprising an ultra-high voltage source of about 110 kV connected to the target and configured to accelerate the deuterium and tritium ions from the central region of the cavity within the cylinder of the accelerating electrode toward the target.
