NBI (Neutral Beam Injection)

Neutral Beam Injection (NBI) is a technique used in nuclear fusion experiments to add energy and heat to a plasma. It involves creating high-energy neutral atoms, typically hydrogen or deuterium, by accelerating charged particles and then converting them into neutral atoms. These neutral atoms are then injected into the hot plasma inside a fusion device like a tokamak. Once inside, they collide with the plasma particles, transferring their energy and raising the plasma’s temperature. This process helps sustain the conditions necessary for nuclear fusion to occur, aiming to produce clean, abundant energy.
