Non-thermal electrical discharges in air at atmospheric pressure, like the dielectric barrier or corona discharges, are the source of electrons, nitrogen and oxygen atoms, various types of reactive species, radicals, atomic and molecular positive or negative ions, different bands of electromagnetic waves, or acoustic waves. Each of these discharge products could be used for various applications, like the production of ozone or nitrogen oxides for environmental or biomedical applications or for the study of plasma interaction with surfaces of various materials in order to modify these surfaces properties. Proposed research is therefore oriented to the study of the non-thermal plasma sources based on the dielectric barrier or corona discharges, diagnostics of the discharges as well as the generated plasma diagnostics. The attention will be devoted to the feedback between the discharge and generated plasma parameters on one side and on the other side on the change in investigated quantity, like the production of active species, or modification in surface properties of materials exposed to the plasma.
