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.

The world’s largest compact-toroid device, C-2, has been upgraded to C-2U at Tri Alpha Energy to achieve sustainment of field-reversed configuration (FRC) plasmas by neutral-beam (NB) injection (NBI) and edge biasing, and the C-2U experiment is characterized by the following key system upgrades:

The world’s largest compact-toroid device, C-2, has been upgraded to C-2U at TAE Technologies to achieve sustainment of field-reversed configuration (FRC) plasmas by neutral-beam (NB) injection (NBI) and edge biasing, and the C-2U experiment is characterized by the following key system upgrades.

Improved density profile measurements in the C-2U advanced beam-driven Field-Reversed Configuration (FRC) plasmas

August 2016 | M. Beall | Review of Scientific Instruments | Paper

In the prior C-2 experiment, electron density was measured using a two-color 6-chord CO2/HeNe interferometer. Analysis shows that high-frequency common mode phase noise can be reduced by a factor of 3 by constructing a reference chord.

Diagnostic suite of the C-2U advanced beam-driven field-reversed configuration plasma experiment

August 2016 | M. C. Thompson | Review of Scientific Instruments | Paper

The C-2U experiment at Tri Alpha Energy studies the evolution of field-reversed configuration (FRC) plasmas sustained by neutral beam injection. Data on the FRC plasma performance are provided by a comprehensive suite of diagnostics that includes magnetic sensors, interferometry, Thomson scattering, spectroscopy, bolometry, reflectometry, neutral particle analyzers, and fusion product detectors.
