The ITER transmission lines (TLs) must be designed to deliver 20 MW from a 24 MW, 170 GHz gyrotron system. Miter bends are the main source of loss for these highly overmoded, corrugated, cylindrical waveguide TLs. Previous estimates have used only a pure HE11 mode for the analysis of the loss due to a miter bend, however higher order modes (HOMs) must be… CONTINUE READING
