Abstract

Systems and methods that facilitate forming and maintaining FRCs with superior stability as well as particle, energy and flux confinement and, more particularly, systems and methods that facilitate forming and maintaining FRCs with elevated system energies and improved sustainment utilizing neutral beam injection and high harmonic fast wave electron heating.

Description

Technical field [0001] The embodiments described herein generally relate to a magnetic plasma confinement system having an anti-field configuration (FRC), and more specifically to a system that facilitates the formation and maintenance of FRC with excellent stability and particle, energy, and flux confinement. The method, and more specifically, relates to a system and method that facilitates high-order harmonic fast wave electronic heating in FRC. Background technique [0002] The anti-field configuration (FRC) belongs to a category of magnetic plasma confinement topology called compact ring (CT). FRC mainly exhibits a polar magnetic field and has a self-generated annular field that is zero or small (see M. Tuszewski, Nucl. Fusion 28, 2033 (1988)). The attractiveness of this configuration lies in its simple geometry for easy construction and maintenance, a natural unrestricted divertor for energy extraction and deashing, and a very high β (β is the average plasma in the FRC The...

Problems solved by technology

Another shortcoming of [0007] existing FRC system designs is the lack of effective electron heating regimes other than neutral beam injection, due to electron Mechanism for power damping, which tends to have poor electronic heating efficiency
