抄録

Neoclassical radial electric fields are calculated in a tokamak plasma with a flow by using a δf Monte Carlo particle simulation code “FORTEC-S” . The calculations are restricted to the plasma with a constant temperature. The distribution function related to the given flow is treated as a perturbation to the background Maxwellian distribution function in the simulation. The time development of the radial electric field is analyzed by a simple model and the average radial electric field is estimated in the long time limit. It is shown that the δf simulation results are well in agreement with those of the analytical estimation.
