Electron beam storage devices for controlled fusion

The current status concerning the storage of electrical energy is examined. Attention is given to the confinement of unneutralized plasma and the possibilities for energy storage provided by an intense relativistic electron beam. The electrostatic heating of a Tokamak is considered along with questions of electron beam formation, stability problems, and approaches for fusion with high-density pellets. One approach proposed for achieving fusion involves the containment of a high-energy electron beam in a torus under conditions of high vacuum. D-T pellets are to be injected into the beam. The pellets would be converted into plasma which could be heated by the electrostatic energy associated with the confined, unneutralized beam.
