The upgraded 3.7 GHz Lower Hybrid Current Drive (LHCD) system for the Tore Supra (TS) tokamak is in the process of installation. When complete, it will permit long pulse injection (1000s) at coupled power level up to 6, 5 MW. Steady state operation of high power RF sources and components is challenging and requires careful validation before the system can be commissioned on the tokamak.Results on the validation of CW klystrons, improvements on the RF components forming part of the power generation circuit and the development of an RF water load to sustain CW pulses under 700 kW RF power are presented.
