Measuring dynamic fast ion spatial profiles with fusion protons in the Madison Symmetric Torus

Neutral beam injected fast ions play a dominant role in both the field reversed configuration (FRC) at TAE Technologies and the Madison Symmetric Torus (MST) reversed field pinch (RFP), making fast ion diagnosis a major pillar of both research programs.

Performance Improvement of a Magnetized Coaxial Plasma Gun by adopting Iron-Core Bias Coil and Pre-Ionization Systems

Performance Improvement of a Magnetized Coaxial Plasma Gun by adopting Iron-Core Bias Coil and Pre-Ionization Systems

A magnetized coaxial plasma gun (MCPG) is utilized to generate a compact toroid (CT). An MCPG-type CT injector had been developed as a particle refueling system for C-2/C-2U field-reversed configuration (FRC) plasmas. To inject CTs repetitively for a long-lived plasma, the injector has been upgraded.

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

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

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.
