Normally ions are considered to be at different temperature than other species in plasmas. My question is : How does ion-neutral collision effect ion temperature in a plasma ?

  • Usually, neutrals got ionized in the plasma. However neutral beams are used to heat the plasma in Tokamaks. If the interaction time is large electron energy is transferred into the ions. The heat capacity of electrons is much less compared to ions, hence ions can not reach a very high temperature. – hsinghal Jan 15 '23 at 14:27
  • If the ion-neutral collision is less, will the ions have a higher temperature than when ion-neutral collision is higher ? Let's assume the neutrals are at room temperature. – bubucodex Jan 17 '23 at 03:48
