Abstract

Electron cyclotron resonant heating of the plasma in the Texas Experimental Tokamak (TEXT) has been achieved with a single gyrotron system, which is presently being expanded to a three-gyrotron system. Each gyrotron can deliver up to 200 kW of RF power into the plasma. Future expansion includes a fourth gyrotron capable of delivering an additional 500-kW of RF power into the plasma. The overall system architecture is described. The overall grounding scheme and the high-voltage power-distribution system are also discussed. Utilizing fiber-optic links in the control system to reduce noise problems associated with high-voltage systems, provide high-voltage isolation, and eliminate ground loops is discussed
