ECH launchers typically use a moveable mirror to steer a gyrotron beam. Increased power handling capability in an ECH launcher requires adding mass or active cooling to the mirrors. The additional forces on the moveable mirror resulting from either approach typically require a compromise between the power handling capability and the steering capability. The P2001 launcher designed by PPPL for DIII-D will launch two 800 kW beams for 10 seconds every 10 minutes. Poloidal and toroidal steering during and between pulses, and a fast poloidal scan capability, will be provided. These conflicting design requirements are satisfied by the use of an innovative steering mechanism. The entire scanning range about two axes is obtained with a mechanism that is strong enough to withstand the electromagnetic forces on the mirror. An innovative mirror design uses high thermal conductivity materials arranged in a manner that limits the eddy currents during a disruption. In this paper, the design of the P2001 launcher is pre...
