Direct observation of ion acceleration from a beam-driven wave in a magnetic fusion experiment

March 2019 | R.M. Magee | Nature Physics | Paper

Efficiently heating a magnetically confined plasma to thermonuclear temperatures remains a central issue in fusion energy research. One well-established technique is to inject beams of neutral particles into the plasma, a process known as neutral beam injection.

Global simulation of ion temperature gradient instabilities in a field-reversed configuration

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.

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.

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.
