1. A neutron generator comprising:

  • a housing configured for incorporation in a subsurface logging tool, the housing defining an ion source chamber for holding an ionizable gas;

    a nano-emitter arrangement comprising multiple nano-emitters located in the ion source chamber and configured for emitting electrons into the ion source chamber;

    an electrode arrangement configured to provide an electric field in the ion source chamber for propelling the emitted electrons through the ionizable gas, to cause ion production by electron impact ionization of the ionizable gas; and

    a permanent magnet that provides a magnetic field configured to act on the emitted electrons, in at least part of the ion source chamber, in misalignment with the electric field.
