Performance of the ECH Transmission Lines and Launchers in DIII-D

The efficiency of the transmission line for the 110 GHz ECH system was measured in DIII-D using a low power rf source. The measured efficiency was about 10% lower than expected from theoretical analysis of the components. The launcher temperature increase during rf pulses was measured and the peak m...

Zusammenfassung:	The efficiency of the transmission line for the 110 GHz ECH system was measured in DIII-D using a low power rf source. The measured efficiency was about 10% lower than expected from theoretical analysis of the components. The launcher temperature increase during rf pulses was measured and the peak mirror surface temperature was inferred from a simulation.
