Enhanced collisionless heating in a nonuniform plasma at the bounce resonance condition
- Department of Physics and Astronomy, University of Toledo, Toledo, Ohio 43606-3390 (United States)
The importance of accounting for a nonuniform density profile for modeling of collisionless electron heating in a bounded low-pressure plasma is demonstrated. A drastic enhancement of the power transfer into an inductive plasma under the condition of a bounce resonance is observed if the nonuniformity of the plasma density profile is accounted for. This enhanced plasma heating is attributed to the increase of the number of resonant electrons, for which the bounce frequency of electrons confined inside the plasma potential is equal to the rf field frequency.
