Fast-Ion Axial Bounce Resonance in a Linear Magnetic Fusion Device

May 2026 | S. Karbashewski | Physical Review Letters | Paper

We report observations of an energetic-particle mode (EPM) in a linear plasma device that corresponds to an axial bounce resonance of fast ions sourced from neutral-beam injection (NBI). In our experiment, novel dynamic shaping of a magnetic mirror field reduces the distance …

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.

First measurements of p11B fusion in a magnetically confined plasma

February 2023 | R. Magee | Nature Communications | Paper

Proton-boron (p11B) fusion is an attractive potential energy source but technically challenging to implement. Developing techniques to realize its potential requires first developing the experimental capability to produce p11B fusion…

Overview of C-2W: high temperature, steady-state beam-driven field-reversed configuration plasmas

October 2021 | H. Gota | Nuclear Fusion | Paper

TAE Technologies, Inc. (TAE) is pursuing an alternative approach to magnetically confined fusion, which relies on field-reversed configuration (FRC) plasmas composed of mostly energetic…

Direct observation of ion acceleration from a beam-driven wave in a magnetic fusion experiment

Direct observation of ion acceleration from a beam-driven wave in a magnetic fusion experiment

March 2019 | R.M. Magee | Nature Physics | Paper

Efficiently heating a magnetically confined plasma to thermonuclear temperatures remains a central issue in fusion energy research. One well-established technique is to inject beams of neutral particles into the plasma, a process known as neutral beam injection.
