Transmission lines for microwave radiation of powerful continuous wave gyrotrons

Electron cyclotron systems of fusion installations are based on powerful millimeter wave sources - gyrotrons, which are capable now to produce microwave power more then 200 kW in CW regime and up to 1 MW in very long (hundred seconds) pulses. There are many transmission lines and components for various plasma installations developed at IAP/Gycom. This paper presents the main test results on gyrotron and transmission line 82.7 GHz/200 kW/CW for tokamak SST-1 (Ahmedabad, India).
