  • Ion-sound velocity at the plasma edge in fusion-relevant plasmas [Elektronski vir]
    Jelić, Nikola ; Kos, Leon, 1966-
    The plasma-sheath boundary is confirmed to be a surface at which the ion directional velocity ui towards the wall attain the ion-sound velocity (so called sonic point, or Mach-1 point). Expressing ... this statement quantitatively is a complex task, which has been solved relatively satisfactorily only for low temperature plasmas, where the ion temperature is negligible with respect to the electron population temperature (so called cold-ion plasmas). In this paper we tackle this problem for so called warm-ion plasmas, in which the ion temperature is arbitrary. Proposed methodis perfectly suited for fusion-relevant plasmas.
