Abstract
A chamber cross-sectional multi-stage plasma arrangement characterized by escalating charge movement towards chamber center axis through one or more escalation stages contributing to the heating of the plasma, the centering of the plasma on the chamber axis, and creating rotation of the plasma therein. Rotation of the plasma around its axis induces a self-generated magnetic field, which in turn increases plasma stability and confinement. Some of the said stages of the multi-stage arrangement may be created by physical elements and components while others may be induced or generated by externally applying magnetic and/or electric fields or their combinations and/or by injection of electrons, ions or other plasma.
