To initiate a sustained fusion reaction, it is usually necessary to use many methods to heat the plasma, including RF heating, electron cyclotron resonance heating (ECRH), ion cyclotron resonance heating (ICRH), and neutral beam injection. Neutral Beam Injection (NBI) involves injecting a high-energy beam of neutral atoms, typically a hydrogen iso...

<radiobiology> This is one of the fundamental plasma heating methods. A particle accelerator is used to create fast ion beams (the particle energies are on the order of 100 keV), the ion beam is then passed through a neutral gas region, where the ions neutralise via charge-exchange reactions with the neutral gas. The neutralised beam is then ...
