Study on synergy of electron-cyclotron and lower-hybrid current drive in Tokamak
托卡马克中电子回旋波与低杂波协同驱动的物理研究

The mechanisms of the synergy effects between electron-cyclotron and lower-hybrid current drive and the synergy current are revealed. The matching relationships required by synergy effect in phase space and on current profile are explained. The non-linear relationship between synergy current and wave power is shown by computer simulation, and its physical explanation is given. This work provides physical support for the design and analysis of relevant experiment.
