Plasmas at atmospheric pressure: Overview on Physics and Applications — Ronny Brandenburg1, 2 and •Hans Höft1 — 1Leibniz-Institut für Plasmaforschung und Technologie e.V., Greifswald, Germany — 2Universität Rostock, Rostock, Germany
Plasmas at atmospheric pressures gain more and more attention, both in research and industry. A variety of plasma sources exist and the applications span a wide spectrum from material processing and chemical conversion to surface treatment and therapeutic usage. Despite the wide use and application, there are still challenges from the fundamental point of view. These plasmas are often characterized by rapid gas breakdown, transient and erratic behaviour, and formation of instabilities.
The tutorial gives an introduction about plasmas at atmospheric pressure. The principles of plasma generation at elevated pressures, in particular the breakdown mechanisms will be explained in the first part of the tutorial.
Plasmas at atmospheric pressure span a wide range of types with different parameters. The most general distinction is made between thermal and non-thermal plasmas. Both forms, its generation and the technologcial applications are explained.
