Nano-emitter ion source neutron generator

A neutron generator comprising:

• a housing defining an ion source chamber;
• an electron nano-emitter arrangement comprising multiple field electron emitters located in the ion source chamber;
• an electrode arrangement comprising an anode separated from the electron nano-emitter arrangement by a separation space by a separation space, wherein the separation space holds an ionizable gas, and wherein the anode is substantially annular and co-axial with a longitudinal axis of the ion source chamber;
• and
• a permanent magnet that provides a magnetic field in misalignment with an electric field generated by the electrode arrangement.
