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…

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 …
