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.

Field-reversed configurations (FRCs) are axisymmetric,
compact plasmas characterized by high β (the ratio of kinetic
to magnetic pressure).

A combined millimeter wave and CO2 interferometer on the C-2W Jet plasma

September 2018 | R. Smith | Review of Scientific Instruments | Paper

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.

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.
