N2 - Temperature Screening Effect (TSE) on the impurity transport in fusion plasmas has been studied by a kinetic Monte Carlo simulation model [Y. Homma and A. Hatayama, J. Comput. Phys. 250, 206 (2013)]. The TSE drift is induced by the background-plasma tempetature gradient across the magnetic field, and is dependent on various parameters of the impurity species as well as on the background-plasma condition. A series of test simulations has been performed in wide range of parameter space. It has been confirmed that the parametric dependences of the TSE drift are correctly reproduced by our kinetic model.
