A combined mmwave and CO2 interferometer on the C-2W Jet plasma

April 2018 | R. Smith | HTPD2018 | Poster

The C-2W device at TAE Technologies is now operational and represents another major step in a progression of advanced beam-driven Field-Reversed Configuration (FRC) confinement devices that have prolonged the lifetime, increased the stability and have added significant neutral beam injection power to heat.

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

April 2018 | R. Magee | 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

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].

Diagnostic Suite of the C-2W Advanced Beam-Driven Field-Reversed Configuration Plasma Experiment

April 2018 | M. Thompson | HTPD2018 | Poster

The new C-2W experiment (also called “Norman”) at TAE Technologies, Inc. studies the evolution of field-reversed configuration (FRC) plasmas sustained by neutral beam injection. Data on the FRC plasma performance is provided by a comprehensive suite of diagnostics that includes over 600 magnetic sensors.

Development of a Zeff Diagnostic Using Visible and Near-infrared Bremsstrahlung Light for the C-2W Field-Reversed Configuration Plasma

April 2018 | M. Nations | HTPD2018 | Poster

The presence of impurities can significantly affect plasma performance since they can account for substantial radiative power losses. To keep impurity content of the plasma low, mitigating strategies (e.g., wall conditioning by titanium gettering) are employed to help pump neutrals and reduce wall recycling

First time-resolved electron density measurements in the C-2W Advanced Field Reversed Configuration plasmas from long-path compact second-harmonic interferometer

April 2018 | M. Beall | HTPD2018 | Poster

The C-2W experiment is an axially symmetric device with formation sections producing and accelerating plasmoids via theta-pinch which collide in a central confinement vessel (CV) and form a hot, stable FRC
