The final design of the ITER equatorial launcher has being implemented. The RF prototype testing to validate the millimeter wave design of the launcher was carried out and the results confirmed the steering range and quality of mm-wave beam and in-directly the transmission efficiency.}, title = {Development of MW Gyrotrons and Equatorial Launcher for ITER}, year = {2017} }
