Preliminary study of ECE imaging concept for W7-X, using the Talbot effect in rectangular waguides — •Daniel Iglesias1, Burkhard Plaum1, Walter Kasparek1, Matthias Hirsch2, and Thomas Hirth1 — 1IGVP, Universität Stuttgart — 2Max-Planck Institut für Plasmaphysik, Greifswald
For spatially resolved measurements of Electron Cyclotron Emission (ECE) in W7-X, an imaging antenna based on a corrugated rectangular waveguide can be used. The imaging characteristics of the antenna allow a simultaneous operation at multiple angles and frequencies. As a result it is possible to localize a set of points inside the plasma, where the ECE can be measured without the need of mobile components facing the plasma.
