Communications & Power Industries (CPI) has recently fabricated two gyrotrons designed to produce a megawatt of output power. The first system is a 110 GHz, 1.2 MW, 10-second-pulse gyrotron to be used for electron cyclotron heating and current drive on the DIII-D tokamak at General Atomics (GA). This gyrotron has completed factory testing, where it demonstrated 1.2 MW output power for short pulses, and 480 kW output power for 10-second pulses at the 25-A CW current limit of CPI's test facility. It has been shipped to GA, where it will be tested to full parameters (1.2 MW, 10 seconds). The second system is a 170 GHz, 500kW–1MW, CW gyrotron to be used by the U.S. ITER team for ECH transmission line component testing and qualification. This gyrotron is currently (as of June 2012) being factory tested.
