Among various advanced fuel cycles, proton-boron-11 (p-11B) fusion has attracted renewed interest as a potentially clean and sustainable fusion energy source.
This aneutronic fusion concept has long been envisioned as an ultimate cleaner fusion reactor scheme…

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…

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…

Fast ion tail was observed at more than the injection beam energy of 15 keV. In particular, the effective tail temperature of fast deuterium ion was notably high

In order to measure the fast ion using NPAs in the low neutral density core region of a magnetic confinement fusion device, active change exchange measurements are often performed using a NB as a CX target
