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.

Experimental characterization of Alfven modes in a field-reversed configuration plasma

Experimental characterization of Alfven modes in a field-reversed configuration plasma

June 2018 | R.M. Magee | Nuclear Fusion | Paper

High power neutral beam injection into the C-2U advanced field-reversed configuration (FRC) stimulates at least three distinct energetic particle modes, none of which have been linked to
a performance limitation. Here we present an experimental characterization of one mode in particular, a high frequency mode ( f > fci ) observed in the decaying phase of the FRC.

The C-2W device generates a field reversed configuration
(FRC) plasma in a 1.6 m diameter Inconel confinement vessel
(CV) by forming and accelerating two FRCs in opposite direc-
tions to collide and merge in the CV.

Inference of field reversed configuration topology and dynamics during Alfvenic transients

Inference of field reversed configuration topology and dynamics during Alfvenic transients

February 2018 | J.A. Romero | Nature Communications | Paper

Active control of field reversed configuration (FRC) devices requires a method to determine the flux surface geometry and dynamic properties of the plasma during both transient and steady-state conditions.
