            Abstract : 
Oscillation at tri-frequency 170 GHz, 137GHz and 104GHz with more than 1MW were demonstrated with a high-order mode (TE31,11) gyrotron developed for ITER. The successful modification of the ITER equatorial launcher design to enhance off-axis current drive performance and to ensures that mm wave beams from both middle and bottom beam row pass through the same BSM opening that leads to the increase of neutron shielding potential is performed.
