Outline of Final Research Achievements |
The aim of the project is to clarify spatial asymmetry of nonlinear energy transfer function in plasma turbulence which could contribute spatial asymmetry of plasma structure in tokamaks and linear plasma devices. For the purpose, a number of diagnostic probes (high-field side probe, Rogowski probe, composite Langmuir probe, and multi-channle probes) were developed successfully. In addition, computational resources such as a work station and PC cluster were provided to analyze a large amount of data obtained in experiments. In an analysis on the tokamak data, a sign of spatial asymmetry of nonlinear couplings was found. However, we also found that higher precision in experiment and data analysis is required to conclude the asymmetry of nonlinear energy transfer function, which is left for the future tasks.
