Ion particle confinement in field-reversed configurations

June 2025 | L. Steinhauer | Physics of Plasmas | Paper

A system for analyzing equilibria with fully kinetic ions is developed, aimed at understanding ion end-loss rates in field-reversed configurations. The method builds upon the constants of motion in energy-momentum phase space.

Generation of field-reversed configurations via neutral beam injection

April 2025 | T. Roche | Nature Communications | Paper

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 and increase plasma …
