Parasitic mode excitation in gyrotron beam tunnelsFunded under: EAEC-FUSION 12C
Experimental measurements of parasitic oscillations exited in quasi-optical gyrotron (QOG) beam tunnels are presented for different beam tunnel configurations. The observed starting current of such modes can be very low (100 mA), and the frequency is in general less than the maximum relativistic cyclotron frequency encountered in the beam tunnel. Estimations of the emitted RF power in parasitic modes is as high as 2 kW for a beam power of 70 kW.
