| Outline of Final Research Achievements |
We have promoted the study about the non-diffusive transport enhanced under the detached divertor condition by using the Large Helical Device (LHD) and the linear plasma device NAGDIS-II. In LHD, multi-point and high temporal resolution measurements, the magnetic field tracing, and the fast reciprocating probe measurement were carried out in order to investigate the generation position, propagation velocity, and so on. In NAGDIS-II, a measurement in the transient state from attached to detached divertor conditions implied an importance of the ionization-front position for enhancement of the non-diffusive transport. In addition, we applied the newly-made radially and azimuthally separated electrodes to clarify detailed transport characteristics.
