A combined mmwave and CO2 interferometer on the C-2W Jet plasma
April 2018 | 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 | 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].
FIDA Diagnostic Development for the C-2W Field-Reversed Configuration Plasma
April 2018 | HTPD2018 | Poster
TAE’s advanced, beam-driven field-reversed configuration device has a large fast-ion population, allowing for fast-ion D-alpha (FIDA) studies. Development of a FIDA spectrometer for the new C-2W device is underway.
Diagnostic Suite of the C-2W Advanced Beam-Driven Field-Reversed Configuration Plasma Experiment
April 2018 | 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 | 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
Particle and Heat Flux Diagnostics on the C-2W Divertor Electrodes
April 2018 | HTPD2018 | Poster
An array of diagnostics was installed across the divertor electrode plates of C-2W.
They are well-situated to study electron heat transport on the open field line plasma that surrounds the FRC.
First time-resolved electron density measurements in the C-2W Advanced Field Reversed Configuration plasmas from long-path compact second-harmonic interferometer
April 2018 | 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
Combination Doppler Backscattering / Cross-Polarization Scattering Diagnostic for the C-2W Field-Reversed Configuration
April 2018 | HTPD2018 | Poster
A versatile combination Doppler Backscattering (DBS) and Cross-Polarization Scattering (CPS) diagnostic for the C-2W Beam- Driven Field-Reversed Configuration is described.
Thomson scattering systems on C-2W field-reversed configuration plasma experiment
April 2018 | HTPD2018 | Poster
Thomson scattering process is that when laser fires into plasma, plasma electrons oscillate in the laser field and radiate.
