Abstract

A flux sustainment condition of field-reversed configurations (FRCs) is given in the present paper for the first time. Here, maintenance of the poloidal flux is considered to be accomplished by tangential neutral beam injection (NBI). The beam current of 700 A is estimated analytically to be required for a flux balance of an FRC with the resistive anomaly factor of 10.

Keywords
