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.

Numerical study of FRC stabilization in C-2W with external actuators

November 2025 | R. Groenewald | APS DPP 2025 | Presentation

Overview of NORM (C-2W) Fusion Device –
NORM uses Neutral Beams and End-Biasing Systems to form and sustain either Mirror Plasmas or Field-Reversed
Configurations (FRCs) – see Roche et al., Nature Comm, 16, 3487 (2025) for NBI formed FRC report.
