Electrostatic confinement

Electrostatic confinement uses electric fields to contain hot plasma—charged particles like ions and electrons—inside a specific area. By applying carefully arranged electric potentials, the fields create barriers that keep the plasma from escaping, enabling it to reach and maintain the high temperatures needed for fusion reactions. Unlike physical walls, electrostatic confinement relies solely on electric forces to control the plasma, making it a key concept in plasma physics and energy research aimed at developing sustainable fusion power.
