The mission will shift more in the direction of plasmas for sustainable technology. To proceed along these lines the research has to focus on plasma generation and processing. Consequently, our efforts should be directed to integrate the three competence areas of plasma physics, pulsed power technology and chemical process technology.
The pulsed power laboratory will be upgraded with a full diagnostic facility for pulsed plasmas, including tools for electron energy and distribution detection, radical species and distribution, plasma imaging, voltage, current and power, chemical analysis. In collaboration with industry, the feasibility program will accelerate: application-directed research is stimulated on solutions by plasma processing for difficult emission problems (dioxin, H2S, hydrocarbons). Conditioning of syngas derived from biomass gasification is another important target of the applications research.
The IOP-EMVT part of the pulsed power program will see the following developments:
Two IOP projects will be successfully concluded with a thesis “Efficient plasma processing and multiple switching systems”. A new IOP project has been granted. It concerns an innovative concept to energize a corona-plasma reactor. The concept utilizes magnetic pulse compression techniques. A major feature of this method is that a high-voltage switch is not required for pulse generation.
Also in this project a network model for a corona reactor and a multiple-streamer model will be developed and integrated into a combined model for corona-plasma systems. The aimed result will be an operational tool for the control of the interactions between power modulator, corona discharge and chemical activity within the reactor.
The two STW projects within the programme are stepping up. In “Pushing the frontiers of High-Voltage Pulse Technology” much effort will be put into developing a switch at the input of the parallel TLT channels. This switch must be fast (less than 1 ns), high current and very low output impedance. A possible solution is a switch based on a surface discharge over a dielectric material with very high dielectric permittivity. The STW project on streamer development will more and more focus on multiple simultaneous streamer processes.
The applications part of the program will see increasing activities due to increasing industry involvement.
The Corona Feasibility program with industry will be directed towards industrial odor reduction, including an experimental and demonstration programme. The ultimate goal is development of prototype plasma devices for industry. Work with industry will grow with activities in number of proposed application areas. For example in 2007 is the investigation of the favorable effects of special plasma structures on surface properties of various substrates.In the work on biogas conditioning and plasma catalysis new solutions will be investigated by combining corona with other techniques such as partial oxidation and multistage, hydrogenation catalysts. The application area of pulsed power driven fracture will further be developed.
