| Abstract: | The effect of radial diffusion of electrons on current generation by electron-cyclotron waves in a tokamak plasma is studied in the framework of the three-dimensional kinetic model. A numerical solution of the problem is obtained. The results suggest that electron diffusion in the radial direction has a significant effect on the energy spectrum of the excited current. The lower diffusion bound in the velocity space plays an important role in this context.Translated from Matematicheskie Modeli Estestvoznaniya, Published by Moscow University, Moscow, 1995, pp. 27–31. |
