Claim:
1. A helical ion accelerator and neutron source comprising: an ion source forming a source of deuterium ions; a dielectric pipe defining an outer surface, an inner vacuum chamber, and defining an axis of the dielectric pipe; an outer conductive wire wound about the dielectric pipe outer surface to form a coil of wire which is circumferentially wrapped to form turns around the outer surface so that the turns are spaced along the axis; wherein the conductive wire forming a part of the coil defines a proximal end and a distal end, and wherein the outer surface of the dielectric pipe extends from the proximal end to the distal end; wherein the inner vacuum chamber is connected to a source of vacuum; an outer metal pipe which is coaxial with the axis of the dielectric pipe, the outer metal pipe defining an inner surface which is spaced from the outer surface of the dielectric pipe, and from the coil of wire wrapped around said outer surface; a 100 to 300 kV pulse wave voltage source connected to the proximal end of the coil through, a resistive column, or an induction coil of at least one turn, or wherein said pulse wave voltage source is a charge on the outer metal pipe connected to the proximal end of the coil through or by a high-voltage switch; wherein the ion source is connected to the dielectric pipe in ion supplying relation to the inner vacuum chamber at the proximal end so as to inject ions into the inner vacuum chamber along the axis of the dielectric pipe; wherein the helical ion accelerator is tapered in impedance along the axis of the dielectric pipe from the proximal end to the distal end so that impedance is reduced from the proximal end to the distal end; a beam focusing device selected from the group consisting of: a solenoid magnet of at least 0.25 Tesla defining an inner solenoid cavity, said cavity symmetrically aligned along the axis so that the outer metal pipe with solenoid magnet surrounds the coil and the dielectric pipe, at least one radial multi-pole focusing magnet, and an electrostatic focusing beam optic; and a target positioned along an extension of the axis, so as to produce a beam of neutrons through fusion.
