@article{5811, author = {A. Montvai}, title = {Particle drift trajectories in the rotating field of the dynamic ergodic divertor in the TEXTOR tokamak - A Monte Carlo study}, abstract = {Statistical properties of the guide center trajectories are analyzed in the boundary region of the TEXTOR tokamak. The magnetic configuration investigated is a static magnetic field model consisting of a typical TEXTOR equilibrium with the following parameters: B-T= 2.2 T at the magnetic axis, and a limiter q value of q(a) = 4.2 and a perturbation. The perturbing field is created by the dynamic ergodization divertor (DED) coil system with a nominal current value of 10 kA. Both of the possible methods of operation: the static and the rotating one have been analyzed. Based on a randomly generated ensemble of 7 x 10(3) initial conditions the main statistical properties of the trajectories are reported.
