“…Another concept utilizes two coaxial cylindrical magnetic field coils with parallel currents which induce a plasma current within the annulus between them [11]. Such plasmas have been generated experimentally, although on dynamic time-scales [12,13 ]. In this paper, we calculate the time evolution of a quasi-static Ohmically heated FRC, independent of the specific formation technique, provided it is capable of increasing the internal poloidal magnetic flux of the FRC; similar analyses applied to the RMF current drive technique have been reported [14,15].…”

Zero-dimensional power balance calculations are performed for a quasi-static, purely Ohmically heated field-reversed configuration. Without compression, the constraint imposed by radial pressure balance limits the power input. Estimates of the energy loss from impurity line radiation as well as from classical and anomalous transport are given. Effects of cold puff gas injection are also investigated.

“…The first AFRC device was developed in 1963 by Phillips et al [55] to study the formation physics of plasmoids for fusion experiments. Several other groups implemented similar configurations, and in 1967 Alidieres et al [56] demonstrated the first translation of an AFRC plasmoid. To accomplish this, a radial magnetic field created by an iron circuit was introduced.…”

An inductive pulsed plasma thruster (IPPT) operates by pulsing high current through an inductor, typically a coil of some type, producing an electromagnetic field that drives current in a plasma, accelerating it to high speed. The IPPT is electrodeless, with no direct electrical connection between the externally applied pulsed high-current circuit and the current conducted in the plasma. Several different configurations were proposed and tested, including those that produce a plasma consisting of an accelerating current sheet and those that use closed magnetic flux lines to help confine the plasma during acceleration. Specific impulses up to 7000 s and thrust efficiencies over 50% have been measured. The present state-of-the-art for IPPTs is reviewed, focusing on the operation, modeling techniques, and major subsystems found in various configurations. Following that review is documentation of IPPT technology advancement paths that were proposed or considered.

“…The AFRC formation studies suggest that an AFRC plasmoid source would be suitable for space propulsion technology, yet AFRC plasmoid translation (acceleration) has never been thoroughly investigated. An early fusion experiment by Alideres, et al [18] used an annular plasmoid source with permanent magnets to eject a deuterium plasmoid,…”

“…The translation of an AFRC plasmoid in a fusion study [18] was achieved with a cylindrical geometry using permanent magnets to accelerate the plasmoid. Permanent magnets add significant mass to a propulsion system, limiting its attractiveness.…”
