Study on operating parameters space of tokamak plasma with low hybrid current drive

Employing the core scrape of layer divertor (C S D) model, we analyze the operating parameters space of tokamak plasma in the phase space of particle flow and heat flow. The influences of impurity radiation, gas puffing in the edge of the device and bootstrap current in the core plasma for the operating parameters space of tokamak device are investigated in some detail. Results show that increasing the impurity radiation, gas puffing in edge region and raising the bootstrap current fraction are effective methods for improving the operating parameters region for the tokamak plasma.
