WebThe present system for ECCD on the DII-D tokamak consists of two gyrotrons operating at 110 GHz. The system and verification of its proper operation have been described in detail elsewhere [1,2], so only a brief description will be given here. The two gyrotrons are rated for 0.9 MW for 2 s and 0.8 MW for 1 s, respectively. http://www-naweb.iaea.org/napc/physics/FEC/FEC2012/papers/169_EXP312.pdf
