Plasma heating is a critical process in achieving the high temperatures necessary for nuclear fusion reactions, where energy is produced by fusing atomic nuclei. Various methods like ohmic heating, radiofrequency heating, and neutral beam injection are employed to increase the kinetic energy of particles within the plasma, facilitating the conditions needed for sustained fusion reactions.

Radiofrequency heating is a process that uses electromagnetic waves in the radiofrequency range to generate heat within a material, typically used for industrial, medical, and food processing applications. It offers rapid and uniform heating, making it efficient for processes like polymer curing, tumor ablation, and pasteurization.

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.
