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.

Plasma Physics

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.

Magnetic fields are invisible forces generated by electric currents and magnetic materials, influencing the behavior of charged particles in their vicinity. They play a crucial role in various natural phenomena and technological applications, from Earth's magnetosphere to electromagnetic devices.

Magnetic Fields

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.

Fusion reaction is a nuclear process where two light atomic nuclei combine to form a heavier nucleus, releasing a significant amount of energy. It powers the sun and holds potential as a clean and nearly limitless energy source if controlled fusion can be achieved on Earth.

Fusion Reaction

Energy transfer is the process by which energy moves from one system or object to another, often changing form in the process. This fundamental concept is crucial for understanding various physical phenomena, from biological processes to mechanical systems and thermodynamics.
