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 …

Enhanced plasma performance in C-2W advanced beam-driven field-reversed configuration experiments

October 2024 | H. Gota | Nuclear Fusion | Paper

TAE Technologies’ fifth-generation fusion device, C-2W (also called ‘Norman’), is the world’s largest compact-toroid device and has made significant progress in field-reversed configuration (FRC) plasma performance.

Demonstration of aneutronic p-11B reaction in a magnetic confinement device

August 2024 | K. Ogawa | Nuclear Fusion | Paper

Aneutronic fusion using commonly available fuel such as hydrogen and boron 11 (11B) is one of
the most attractive potential energy sources. On the other hand, it requires 30 times higher
temperature than deuterium–tritium fusion in a thermonuclear fusion reactor condition.
