Abstract

Poloidal and toroidal electric fields generated by electron cyclotron heating are studied in a helical plasma. A linearized Fokker-Planck equation is solved by the adjoint method, assuming a helically symmetric configuration for simplicity. It is found that the poloidal and toroidal electric fields are generated near the bottom of the magnetic ripple, and that the larger radial flux is enhanced in a helical plasma compared with that in a tokamak plasma.
