DIAGNOSTICS OF SURFACE-PLASMA FORMATIONS
IN A PULSED SURFACE DISCHARGE

UDC 533.9.08

The main parameters (temperature and electron concentration) 
of the plasma formed in the near-wall and near-electrode regions of 
a high-current pulsed surface discharge with separate torches at atmospheric 
and lower pressures have been determined and analyzed. The mechanism 
of failure of the face (working) surface of cylindrical electrodes 
and a dielectric surface has been investigated on the basis of analysis 
of heat flows. The surface and open discharges were compared.
