First experimental measurements of a new fast ion driven micro-burst instability in a field-reversed configuration plasma

First experimental measurements of a new fast ion driven micro-burst instability in a field-reversed configuration plasma

October 2018 | B. Deng | Nuclear Fusion | Paper

In modern F experiments at TAE Technologies, classical FRC instabilities are suppressed
by advanced neutral beam injection and edge biasing methods, leading to high plasma confinement and fast ion pressure built-up which is comparable to the bulk plasma pressure.

Theory of ion dynamics and heating by magnetic pumping in FRC plasma

Theory of ion dynamics and heating by magnetic pumping in FRC plasma

July 2018 | J. Egedal | Physics of Plasmas | Paper

A new mathematical framework is developed for efficient evaluation of ion heating during magnetic pumping of field-reversed configuration (FRC) plasmas. The topology of ion trajectories is examined through the use of action variables applied to a typical FRC equilibrium.

Coupled transport in field-reversed configurations

Coupled transport in field-reversed configurations

February 2018 | L. Steinhauer | Physics of Plasmas | Paper

Coupled transport is the close interconnection between the cross-field and parallel fluxes in differ- ent regions due to topological changes in the magnetic field. This occurs because perpendicular transport is necessary for particles or energy to leave closed field-line regions, while parallel transport strongly affects evolution of open field-line regions.
