Abstract :
Electrons can be confined in a “bumpy torus” so that they are effectively trapped by mirror magnetic fields and do not circulate around the torus. This has been confirmed by experiments at Maxwell Laboratories. Based on this result, we propose a heavy ion accelerator in which ions are confined and focused by the net space charge of the electrons. Then an inductively applied toroidal electric field of about 10 Volts/cm will accelerate ions without, accelerating electrons. The reason for this is that, whereas the electron dynamics is adiabatic, the ion dynamics is not and the magnetic fields have little effect on ions. In this paper, this conjecture is proven, self-consistent equilibria for electrons and ions are obtained and stability problems are investigated. A conceptual design is evaluated in which Uranium ions are accelerated to produce 100 Terawatt pulses at 100 GeV. The major radius of, the torus required is 3 – 5 meters, and the design is based on existing technology.
