Abstract

Filamentary gas discharges at atmospheric pressure, namely dielectric-barrier discharges and coronas, produce highly non-equilibrium plasmas in a controllable way at a moderate gas temperature. They provide the effective generation of atoms, radicals and excited species by energetic electrons. Consequently, they have found many applications, among others in environmental protection. The controlled application of these discharges requires a good understanding of their physical properties and the knowledge of the basic plasma parameters. Milestones on this way and the progress in the plasma diagnostics are listed of. Recently, the technique of spatially resolved cross-correlation spectroscopy (CCS) (with a resolution in the sub-ns and sub-mm range) has been used to contribute to a better understanding of these discharges. The application of the CCS method is described in more detail.
