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.
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.
Neutral beam injected fast ions play a critical role in the C-2 field reversed configuration plasma, helping to sustain magnetic flux against resistive decay and heating the plasma via Coulomb collisions.

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.
