Spark-over of
gas gap on the surface barrier discharge
Abstract
The
development of a discharge channel in barrier discharge with surface
arrangements is investigated numerically. It is found that initial phase of
discharge development is mainly determined by photoemission. The cathode layer,
which appears at the negative electrode, becomes the source of secondary
electrons caused by ion collisions with cathode surface. Parameters of the
cathode layer are near to those of a normal glow discharge. The charge transfer
as well as energy release and ozone production happens mainly in the conductive
channel, which appears above the dielectric surface. It is found that specific
energy consumption on ozone production is near the experimental value and is
determined by field strength in the conductive channel, which is nearly
constant and of about 70 to 100 Td.
