C-2W’s FRC vs Mirror Plasma Characteristics with Varying Bias Voltage

November 2025 | R. Jaber | APS DPP 2025 | Poster

TAE Technologies’ current experimental device C-2W (also known as “Norman”) produces and sustains a steady state field reversed configuration plasma through neutral beam injection, edge biasing, and a robust real-time plasma control system.

Peak density detection and fluctuation properties near the null-field radius in C-2W Field-Reversed Configuration (FRC) plasmas

November 2025 | L. Schmitz | APS DPP 2025 | Poster

Doppler Backscattering hardware has been used to detect the density peak in C-2W FRC plasmas from transmission/reflection transitions.
Main result: The peak density reconstructed from FIR Interferometry (via ABEL inversion) is on average 20-25% lower than the peak density determined via DBS.

Validation of Helium Line-Ratio Spectroscopy for Electron Temperature and Density Measurements in the Fueling Region of C-2W

November 2025 | L. Jian | APS DPP 2025 | Poster

High-fidelity measurements of plasma parameters in the fueling region of the C-2W field-reversed configuration (FRC) device [1] are essential for assessing neutral fueling efficiency, stability characteristics, and tandem confinement properties.

Titanium Gettering: Towards a Physics Diagnostic in Norm

November 2025 | J. Barrett | APS DPP 2025 | Poster

Maintaining ultra-high vacuum is critical for sustaining high-performance field reversed configuration (FRC) plasmas in TAE’s latest fusion device—Norm [1]. Titanium gettering plays a pivotal role in maintaining vessel base pressures of 1 ” 10!” Torr or lower, suppressing impurities in the vessel…

Demonstration of FRC core fueling via pellet injection on open field lines

November 2025 | G. Koumarianou | APS DPP 2025 | Presentation

TAE Technologies experimental device “C-2W/Norm” generates beam-driven field-reversed configuration plasmas for 40 ms.
By implementing a new pellet injection geometry, we experimentally demonstrate core fueling with pellets of steady-state FRCs.
