Plasma temperature

The temperature of the particles (i.e. ions, electrons and neutrals) in the plasma corresponds to the thermal kinetic energy distribution per particle. Usually, the energy distribution function is close to a Maxwellian. Because electrons are much lighter than ions, they will move much faster at the same temperature. In some types of plasma, all the parts are in thermal equilibrium, but more often the electrons are at a much higher temperature than the ions. The temperature of the plasma is therefore usually given as the electron temperature. It is most often measured in electronvolts, with 1 electron volt corresponding to a temperature of approximately 11,600 kelvin.
