There are many definitions about plasma temperature, like electron temperature, ionization temperature, excitation temperature, atomic temperature, ionic temperature... What do they mean? I am kind of confused.
Generally, these particles temperature are related to their kenetic energy or velocity. In many cases, electrons hold different temperature from other particles, since the electrons are much lighter than other heavy particles, and move more rapidly, that is known as 2T plasma.
Plasma temperature is related to the kinetic energy of electrons. Other temperatures are the kinetic energy of electron for generating different effects such as ionization, excitation etc. In some cases plasma has electrons having two temperature, particularly in the case of wave plasma interaction.
