| Abstract: | The simulation of the radial electric field shear, which is responsible for L-H transition by means B2SOLPS0.5.2D transport code, gives the dependence of this shear on plasma parameters. Also, as result of uni-directional neutral beam heating, internal transport barrier is formed and ion radial heat flux q ir starts to decrease. Furthermore, the dependence of radial electric field shear on ion temperature gradient ITG has also investigated. |
