This course is focused on basic properties and processes taking place in plasma, including their diagnostics and possible applications. Students are introduced to plasma thermodynamics and kinetics (non-equilibrium and equilibrium plasma, collision processes, distribution functions, basic transport processes in plasma). Lectures also provide a list of basic methods of plasma diagnostics (spectral, probe, and corpuscular methods). The main part of the course deals with plasma in labs, its properties, particular types of electrical discharges, its generation and possible applications (dc, ac, RF, MW, discharges in liquids, plasma excited at high pressure, capacitive and inductive coupled plasma). A list of plasma chemical processes contains especially reactions in active and post-discharge plasma, surface treatment of various materials, creation of thin layers (PE CVD, PA CVD), plasma polymerization, plasma spraying, sputtering, and etching. Moreover, lasers, plasma displays, and plasma as illumination tools belong to special plasma kinds using assisted chemical reactions.
