Abstract

The 42GHz Electron Cyclotron resonance Heating (ECRH) system is used in tokamaks Aditya and SST-1 to carry out ECRH related experiments at fundamental and second harmonic. The Gyrotron capable to deliver 500kW power for 500ms duration is commissioned in SST-1 tokamak hall and ∼75m long transmission line is laid to connect both the tokamaks. The corrugated waveguide (ϕ63.5mm) based transmission line at normal atmospheric pressure is used to transmit power in HE11 mode. The special feature of this line is that it consists of two waveguide switches, which facilitates to transmit the power in either tokamak without changing any hardware. The total loss in the line is less than 1.1dB.
