Course Objectives
- Understand principles of plasma processes at low and high gas pressures
- Learn about interactions of atmospheric plasma with solids, gases and liquids
- Recognize existing and potential technology application of atmospheric pressure plasma
Course Description
Non-equilibrium atmospheric plasma has many potential applications in coating, surface treatment (e.g. for improving the adhesion or before bonding), in cleaning and activation, sterilization and decontamination. Atmospheric pressure plasma enhanced CVD of films can reach very high rates. Extending plasma-reactive processes up to the atmospheric pressure simplifies experimental systems substantially and, in some cases, brings about economic advantages over reduced pressure technologies.
Technologies using the atmospheric pressure plasma sources bring about fast processes, but it is important to be aware of limits given by atmospheric plasma properties and plasma chemical reactions. The course addresses the most important principles, designs and applications of the atmospheric plasma systems.
