A depollution system for gas treatment, using the repetitive pulsed corona plasmas, has been carried out. For the reactor chamber, various geometries are being tested: (a) point-plate; (b) wire-plate; (c) wire-cylinder. To compare different geometries, the following parameters are measured or calculated: pulsed voltage; pulsed current; electrical charge per pulse; density of the corona electrons; energy dissipation by corona effect. Depending on the geometry, for 25 - 30 kV maximum voltages, the density of the corona electrons is of 1010 - 1011cm-3, and the energy dissipation by corona effect is of 1 - 100 mJ per pulse. Considerations concerning the geometry optimization are proposed.
