QST procures eight ITER gyrotron systems. Continuous operation of 1 MW power was demonstrated in the ITER proto-type gyrotron and fabrications of two ITER gyrotrons were completed. Beam patterns at the window agreed with the design was obtained and 1 MW output power at short-pulse operation was also performed.}, title = {Performance Demonstration Tests for ITER gyrotron}, year = {2017} }
