Abstract

The expansion and upgrading of the electron cyclotron heating and current drive (ECH/ECCD) gyrotron complex on the DIII-D tokamak are continuing with the addition of the first of a series of depressed collector tubes in the 1 MW class. The ultimate goal is a 10 gyrotron system with rapid steering of the rf beams and full integration into the DIII-D Plasma Control System using the real time EFIT equilibrium calculation to determine the ECH/ECCD deposition locations to guide requirements for both steering and injected power.
