The application of the electron cyclotron heating (ECH) and electron cyclotron current drive (ECCD) to the JT-60U tokamak started in 1999. Because the power deposition by the electron cyclotron wave is very localized and controllable, the application

A method for zonal flow study by using direct density fluctuation measurements is proposed. When ambient drift-wave turbulence is modulated by zonal flows (i.e. in the drift-wave-zonal flow systems), an envelope of the ambient density fluctuations ha

2015 40th International Conference on Infrared, Millimeter, and Terahertz waves (IRMMW-THz).
High-power, long-pulse operations of a gyrotron for JT-60SA (Super-Advanced) have been carried out at 110 GHz (1 MW/100 s) and 138 GHz (1 MW/100 s). These results fully satisfied the requirements of the electron cyclotron heating and current drive (E

Data for detecting magnetic flux surfaces at the edge plasma in tokamaks are presented here. When magnetic flux surfaces are moved by a plasma jog, it is observed that a current increment appears in the two sets of double probes whose front surfaces
