The newly designed CVD-diamond Brewster window of the FZK multi-frequency gyrotron requires the existing mirror system to be modified to optimize the transmission through the window aperture. Intensive calculations have been done for this purpose; nine operating modes between 105 GHz (TE/sub 17.6/) and 143 GHz (TE/sub 23.8/) have a nearly fundamental Gaussian distribution at the window. Simulation results show this QO mode converter can be used for the broadband operation of a multi-frequency 1 MW gyrotron.
