Abstract :
The electron cyclotron heating and current drive (ECH/ECCD) gyrotron complex on the DIII-D tokamak is being upgraded with the addition of new gyrotrons. The transmitted power monitoring in the high power millimeter wave transmission system will be upgraded with new rf power monitors sensitive to the wave polarization and mode content. The speed of the real time steering antenna is being increased using a new control system.
