Overview and Initial Results from the Bias Test Stand at TAE

November 2025 | W. Harris | APS DPP 2025 | Poster

The bias system in C-2W has a voltage limitation that is in-part due to arcing between electrodes. The Bias Test Stand (BTS) is a testbed built by TAE to study different electrode configurations and design features to reduce arcing.

Study of the fast-ion acceleration due to the beam-driven modes in C-2W

November 2025 | S. Kamio | APS DPP 2025 | Poster

In C-2U experiments, thermal ion acceleration by a beam-driven wave was observed [R. M. Magee et al. Nat. Phys. 15, 281–286 (2019)]. This thermal ion acceleration is pointed out to dramatically enhance the fusion rate because the beam energy is transferred to thermal ions, bypassing the electron channel…

Electrode Bias Propagation in the C-2W Fusion Research Device

November 2025 | A. Bondarenko | APS DPP 2025 | Poster

TAE Technologies’ fifth-generation fusion research device C-2W1 utilizes neutral beam injection and edge biasing to sustain long-lived, stable field reversed configuration (FRC)2 plasma embedded within a magnetic mirror.

Experimental and Theoretical Progress on Beam-Driven FRCs in the C-2W Device

November 2025 | M. Nations | APS DPP 2025 | Poster

TAE Technologies’ C-2W device has achieved stable, beam-driven Field-Reversed Configurations (FRCs) maintained for up to 40 ms. Recent advances include real-time plasma control, enhanced fueling via pellets and compact toroids, and the commissioning of new cyclotron resonance heating systems.
