High-frequency wave processes in plasmodynamic systems

Resutls of investigations of high-frequency wave processes in plasmodynamic systems - plasma accelerators, non-equilibrium plasma sources, pulsed plasma guns, and other systems, are generalized. Possible mechanisms and the importance of high-frequency wave processes during plasma acceleration are analyzed. Experimental methods of investigations are described; potentialities of diagnostic methods are illustrated by the data on investigations into different types of plasma devices. Prospects of controlling wave processes in plasmodynamic systems are discussed. The methods described and results of investigations into high-frequency wave processes are of interest to many fields of plasma technology
