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

April 2018 | HTPD2018 | Poster

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

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

April 2018 | 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].

Effects of Ionization on Beam Parallel Component and Beam-Driven Perpendicular Modes

October 2017 | APS-DPP | Poster

Experiments indicate beam-driven mode in the vicinity of the ion cyclotron frequency š¯‘›=1 seen at low š¯›½ā€”conditions typically found in C2U FRC scrape-off layer and outbound of separatrix.

Equilibrium properties of hybrid field reversed configurations

January 2017 | 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-2W Field Reversed Configuration Experiment

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

October 2016 | 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.
