1. A neutron generator comprising:

  • a closed housing containing an ionizable gas, the housing defining first and second neutron-generator portions along a longitudinal axis thereof;

    a cylindrical field-ionization structure arranged along an inner surface of the housing in the first portion, the field-ionization structure being configured to ionize the ionizable gas upon application of an electrical voltage to the structure;

    a cylindrical accelerating grid placed about the longitudinal axis in the first portion, the accelerating grid being configured, when operating, to cause accumulation of ions in the grid; and

    a target cathode disposed at an end of the second portion that is distal to the first portion, the target cathode being held, during operation, at a negative electrical potential relative to the accelerating grid to extract ions from the grid and accelerate them towards the target cathode to thereby cause fusion reactions between the ions and target atoms contained in the target cathode.
