Advanced Beam-Driven Field-Reversed Configurations for Aneutronic Fusion

November 2025 | H. Gota | CWFEST 2025 | Presentation

TAE’s goal: p-11B aneutronic fusion Reactivity of p-11B has been reassessed
– Cross section larger than previously believed.
– Kinetic effects can further increase reactivity
– Net effect leads to ~30% increase of the fusion yield for the same…

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…
