Abstract
Under the grant, the applicant has developed a method of identifying poloidal and toroidal modes active in tokamak plasmas. Except complicated situations the method has shown to work well. Even with the limited applications, the advantage from the method is significant and even crucial. The method can be used to identify: (1) responsible coherent modes such as MHD or Resistive modes activity in plasma; (2) onset of instabilities; and can be used for (3) plasma controls. The method has been applied to the DIII-D tokamak experimental data, and some results are presented in this report. The authors also present how the method can be used for plasma controls.
