Increased p-11B fusion reaction rate through fast-ion acceleration by ICRF heating in LHD

November 2025 | S. Kamio | 2025 US-Japan FRC Workshop | Presentation

ICRF heating in LHD clearly accelerates fast ions and enhances p-¹¹B fusion yield. In the FRC device C-2W, fast-ion acceleration is also observed together with beam-driven modes. The n = 2 mode can accelerate NB-injected ions to nearly twice their initial energy…

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…

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.

Generation of field-reversed configurations via neutral beam injection

November 2025 | T. Roche | APS DPP 2025 | Presentation

We report evidence of successful generation of field-reversed configuration plasmas by neutral beam injection. This is achieved by trapping the steady-state beams in an initial seed plasma, hence providing a direct source of toroidally directed energetic ion current …
