Parallel temperature

Definition

Parallel temperature refers to the temperature of a plasma that is measured along the direction of the magnetic field lines. It is an important parameter in understanding how energy is distributed among the particles in a plasma, especially in magnetized environments where the motion of charged particles is influenced by magnetic fields. The parallel temperature helps to assess energy transport and can indicate how effectively heat flows along magnetic field lines.
