Fast-ion D-alpha diagnostic development for the C-2W field-reversed configuration plasma

August 2018 | N. G. Bolte | Review of Scientific Instruments | Paper

TAE Technologies’s advanced beam-driven field-reversed configuration device has a large fast-ion population, allowing for fast-ion D-alpha (FIDA) studies.

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

July 2018 | R. M. Magee | Review of Scientific Instruments | Paper

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.

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.

An Ion Beam System for Absolute Calibration of Neutral Particle Detectors for C-2W

April 2018 | R. Clary | HTPD2018 | Poster

A high-confinement operating regime with plasma lifetimes significantly ex- ceeding previous empirical scaling laws was recently obtained by combining plasma gun edge biasing and Neutral Beam Injection in the C-2U field-reversed configuration (FRC) experiment[1].

Equilibrium properties of hybrid field reversed configurations

January 2017 | M. Tuszewski | Physics of Plasma | Paper

Field Reversed Configurations (FRCs) heated by neutral beam injection may include a large fast ion pressure that significantly modifies the equilibrium. A new analysis is required to characterize such hybrid FRCs, as the simple relations used up to now prove inaccurate.

Neutral Beam Injection System for the C-2U Field Reversed Configuration Experiment

October 2016 | Alex Dunaevsky | APS-DPP | Poster

C-2U Field-Reversed Configuration (FRC) experiment proved substantial reduction in turbulence-driven losses via tangential neutral beam injection (NBI) coupled with electrically biased plasma guns at the plasma ends.
