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.

Measuring dynamic fast ion profiles with fusion protons in the Madison Symmetric Torus

April 2018 | R. Magee | HTPD2018 | Poster

Neutral beam injected fast ions play a dominant role in both the TAE field-reversed configuration (FRC) and the Madison Symmetric Torus (MST) reversed field pinch (RFP), making fast ion diagnosis a major pillar of both research programs.

Fusion proton diagnostic for the C-2 field reversed configuration

August 2014 | R. Magee | Review of Scientific Instruments | Paper

Measurements of the flux of fusion products from high temperature plasmas provide valuable insights into the ion energy distribution, as the fusion reaction rate is a very sensitive function of ion energy.
