THE EUROPEAN 2 MW GYROTRON FOR ITER
Europe is developing a gyrotron capable of delivering 2 MW RF power at 170 GHz in continuous operation (CW) for the ITER EC H&CD system. This paper discusses the advantages and risks of the 2 MW project, the status of the development, and the expected results from the tests planned to start during the 2nd half of 2010 on the industrial gyrotron prototype, which will provide essential elements for the decision between the 2 MW (coaxial cavity) and 1 MW (cylindrical cavity) gyrotron option placed along the track of the European project plan.
