|Abstract: ||In atmospheric-pressure plasmas the main electron heating mechanism is Ohmic heating, which has
distinct spatial and temporal evolutions in the α and γ modes. In γ discharges, ionizing avalanches
in the sheaths are initiated not only by secondary electrons but also by metastable pooling reactions.
In α discharges, heating takes place at the sheath edges and in contrast with low-pressure plasmas,
close to 50% of the power absorbed by the electrons is absorbed at the edge of the retreating sheaths.
This heating is due to a field enhancement caused by the large collisionality in atmospheric-pressure
