Abstract
- Plasma currents have been generated by injecting microwaves at the electron cyclotron resonance frequencies to the Continuous Current Tokamak in the absence of any other power input. The radial profiles of plasma current and particle densities show that the current is driven by the radial flow of electrons acted upon by the selfâconsistent vertical magnetic fields in a way a dynamo acts. Also the energy spectrum of the current carrying electrons shows that the current is carried by the bulk of the plasma electrons and no superthermal electron contribution was detected.
