چکیده انگلیسی
The LHCD (Lower Hybrid Current Drive) system of the SST-1 Tokamak is commissioned for maintaining the plasma current for prolonged periods. The system relies on 4 Klystrons (TH-2103D) to deliver 500Â kW CW power each at 3.7Â GHz to maintain plasma discharge. High power microwave absorbers/dummy loads are required to condition the klystrons at high CW power level and to protect them against reflection. This paper presents a design of a novel and indigenous high power microwave dummy load using water as an absorber. The designed load was analyzed by considering various RF, thermal and mechanical aspects and is 300Â mm in length. It provides excellent matching with an evaluated value of S11 of â38Â dB and VSWR of 1.02:1. Simulation results show that it can absorb almost 99.99% of incident power.
