Project ID: | GA202/08/0419 | Provider: | Czech Science Foundation | Period: | Jan 01, 2008 - Dec 31, 2012 | Principal Investigator: | Ing. Josef Preinhaelter, DrSc. | Co-investigators | J. Urban, J. Zajac, F. Žáček, M. Záruba | Aims of the project: Electron cyclotron emission (ECE) is nowadays already well developed and frequently used plasma diagnostic on tokamaks and stellarators. However, for low magnetic field comparing to plasma pressure it is not possible direct emission of usual electromagnetic ordinary (O) and extraordinary (X) waves. Thus, the only possibility is electrostatic electron Bernstein waves (EBWs), whose propagation is not limited by high density. These waves are converted at the upper hybrid region to X and O modes, which can be consequently detected outside plasma. The applicant has been for many years cooperating with premier world institutions on an EBWs simulation code and its usage for interpretation of experimental results.The project proposes to improve the interpretation of EBW emission via the EBW-X-O mode conversion, enhance the possibilities of EBW emission as a plasma diagnostics and utilize this knowledge for design and optimization of systems for EBW heating and current drive, which are | Results: | Otte M., Laqua H.P., Chlechowitz E., Marsen S., Preinhaelter J., Stange T., Rodatos A., Urban J., Zhang D.: Overview of recent results from the WEGA stellarator.
