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].


FIDA Diagnostic Development for the C-2W Field-Reversed Configuration Plasma

April 2018 | N. Bolte | 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 | 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


Combination Doppler Backscattering / Cross-Polarization Scattering Diagnostic for the C-2W Field-Reversed Configuration

April 2018 | L. Schmitz | 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.


Secondary Electron Emission Detectors for Neutral Beam Characterization on C-2W

April 2018 | J. Titus | HTPD2018 | Poster

Heating, current drive, and partial fueling from neutral beam injection are essential to sustainment of C-2W field- reversed configuration (FRC) plasmas. C-2W has eight 2.1 MW neutral beams (total of 16.8 MW), capable of providing an elliptically-shaped beam of 15 keV hydrogen neutrals for 30 ms.


Measurements of Formation Dynamics in a Multi-Pulse Compact Toroid Injector System

April 2018 | I. Allfrey | HTPD2018 | Poster

The C-2W experiment at TAE Technologies aims at sustaining an advanced beam- driven field reversed configuration (FRC) plasma. However, FRC lifetime is limited by particle confinement, among other factors.
