Formation of a field reversed configuration for magnetic and electrostatic confinement of plasma
First Claim
1. A method for confining a plasma of ions and electrons within a chamber comprising the steps of:
- magnetically confining a plurality of plasma ions within a magnetic field formed within a chamber and having a field reversed configuration (FRC);
forming an electrostatic field within the chamber having a polarity and magnitude that is confining to plasma electrons; and
electrostatically confining a plurality of plasma electrons within the electrostatic field formed within the chamber,wherein both electrostatic confinement of plasma electrons and magnetic confinement of plasma ions occur simultaneously within the chamber;
wherein the step of forming the electrostatic field includes;
applying a magnetic field to the chamber,forming a FRC magnetic field within the chamber about a rotating plasma of ions and electrons, andinjecting neutralized ion beams into the FRC,wherein the magnitude and polarity of the electrostatic field is a function of the magnitude of the applied magnetic field and the velocity of the injected neutralized ion beams.

Abstract
A system and method for containing plasma and forming a Field Reversed Configuration (FRC) magnetic topology are described in which plasma ions are contained magnetically in stable, non-adiabatic orbits in the FRC. Further, the electrons are contained electrostatically in a deep energy well, created by tuning an externally applied magnetic field. The simultaneous electrostatic confinement of electrons and magnetic confinement of ions avoids anomalous transport and facilitates classical containment of both electrons and ions. In this configuration, ions and electrons may have adequate density and temperature so that upon collisions ions are fused together by nuclear force, thus releasing fusion energy. Moreover, the fusion fuel plasmas that can be used with the present confinement system and method are not limited to neutronic fuels only, but also advantageously include advanced fuels.
