HIGH-BETA POLOIDAL PLASMAS AND CURRENT DRIVE BY ECRH ON TOSCA
High-power ECRH has been used on the TOSCA device to produce high values of beta poloidal and to investigate current drive. Plasmas with values of poloidal beta up to 2.5 have been produced by gas puffing and Ohmic heating alone. The value of poloidal beta decreases as the current increases. Experiments and theory on wave driven currents are in reasonable agreement but give low efficiency. This current decreases as the resonance is moved to the outside of the Tokamak, providing possible evidence for the reduction of the current due to trapped electrons.
