Diagnostics and Optimization of Plasma Sources Important for Applications

Systematic investigation of plasma dynamics in magnetoplasma compressor (MPC) is planed for the purpose optimization of plasma flows to the aim of investigation of plasma interaction with surfaces. Numerous effects on the surface of solid targets exposed to MPC plasma will be examined. Various materials will be used and especially materials important for fusion research. Investigation in abnormal glow discharge of Grimm type will be continued, by use of time-space resolved spectroscopy. Spectroscopic investigation of occurrence of energetic atoms (>100 eV) in various discharges will be continued along with numerical simulation. In the Grimm discharge investigations of spectrum of cathode material will be continued in various conditions as well as possible generation of inverse population on levels of sputtered materials of interest for development of UV lasers. The dielectric barrier discharge source (DBD) of original construction has shown high efficiency in destruction of phenols and will be used for treatment of textile dyes, pesticides and medicaments from waste waters. Systematic spectroscopic and other measurements will be performed in order improve destruction of these compounds. The second DBD source will be used for treatment of textile to the aim of improving sorption of silver and gold in the form of ions and nano-particles. For better understanding of DBD operation at atmospheric pressure in helium, time-space distributions of electric filed will be measured.
