Collisionless Electron Heating in RF Gas Discharges: II. The Role of Collisions and Non-linear Effects

Part of the NATO Science Series: B book series (NSSB, volume 367)


  1. 1.

    It is shown that when λ > L, only resonance particles (ωLv x = n) contribute to the heating and as result for large velocities, where the fraction of resonance particles is small, collisionless heating is suppressed.

  2. 2.

    A plateau in the distribution function in the region of first resonance can be observed.

  3. 3.

    At smaller collision frequency the nonlinear effects should be accounted for. If kicks are perpendicular to the discharge boundaries a considerable suppression of collisionless heating appears due to nonlinear effects. In this case collisionless heating is proportional to collision frequency (D ~ v).
