Abstract :
A major upgrade to the electron cyclotron heating complex on the DIII-D tokamak is underway. Two depressed collector gyrotrons are being added to the complex and the transmission lines are being upgraded. Transmission line efficiencies are being increased by reduction in the number of miter bends together with improved alignment resulting in improved mode purity.
