Plasma turbulence in the CASTOR tokamak
Project ID:IAA1043701
Provider:Grant Agency of the Academy of Sciences
Period:Jan 01, 1997 - Dec 31, 1999
Principal Investigator:RNDr. Jan Stöckel, CSc.
Co-investigatorsM. Hron, I. Ďuran, F. Žáček, L. Krlín, V. Petržílka

Aims of the project: Characteristic parameters of the electrostatic and magnetic fluctuations will be measured within the frame of the project, in the scrape of layer as well as in the plasma core of the CASTOR tokamak. The experimental results will be compared with those of the theoretical model of Nedospasov-Endler explaining the plasma edge turbulence as the results of a flute-like instability. A current fluctuations, predicted by the model, will be newly measured in scrape of layer by means of a small-sized Rogowski coil. Besides the electric and magnetic probes, two non-invasive diagnostic method will be developed to measure the fluctations of the plasma core: microwave reflectometer and a detector of H(alpha) fluctuations with a good spatial resolution.Non-inductive polarization of the edge plasma will be studied in a theoretical part of the project.
