TL;DR: In this paper, six 110 GHz gyrotrons have been installed and are operational on the DIII-D tokamak, with a nominal rating of 750 kW and a 2 s pulse length, with the pulse length determined by the maximum temperature allowed on the edge cooled Boron Nitride window.

TL;DR: The DIII-D tokamak has installed a system with three gyrotrons at the 1 MW level operating at 110 GHz as mentioned in this paper, which has achieved good efficiency both for on-axis and off-axis current drive with relevance for control of the current density profile leading to advanced regimes of tokak operation, although there is a difference between offaxis ECCD efficiency inside and outside the magnetic axis.
