In the Collective-Focusing Ion Accelerator (CFIA), electrons are confined by an external magnetic field. The electrostatic field of the electrons serves to confine or focus ions and the acceleration is conventional. In toroidal geometry the acceleration is like a Betatron. The focusing principle was first enunciated by Gabor who showed that the focal length of a lens for ion beams could be reduced by about three orders of magnitude if the magnetic field confines electrons which focus ion beam, compared to using the magnetic field directly. A compact toroidal accelerator based on this principle was described conceptually in two papers written before the contract period. In 1978 an experimental research program was started at the University of California, Irvine (UCI) to apply the focusing principle to a small accelerator system. The objective was to establish the feasibility of a compact high current ion accelerator.
