Neutral Beam Injection (NBI) is a technique used in plasma physics to heat and drive current in fusion reactors by injecting high-energy neutral atoms into the plasma. These neutral atoms penetrate the magnetic fields confining the plasma, transferring their energy through collisions, thereby increasing the plasma temperature and aiding in sustaining the fusion reaction.

Plasma physics is the study of charged particles and fluids interacting with self-consistent electric and magnetic fields, which is fundamental to understanding both natural and artificial plasma phenomena. It has applications ranging from astrophysical processes and space weather to controlled nuclear fusion and industrial technologies.

Fusion reactors aim to replicate the energy production process of the sun by fusing light atomic nuclei, potentially providing a nearly limitless and clean energy source. Despite significant progress, achieving a net-positive energy output remains a major scientific and engineering challenge due to the extreme conditions required for sustained fusion reactions.

Plasma temperature is a measure of the average kinetic energy of particles in a plasma, reflecting how hot the plasma is and influencing its behavior and properties. It is crucial in understanding plasma confinement, stability, and reaction rates, particularly in contexts like nuclear fusion and astrophysics.
