# RF modeling of the ITER-relevant lower hybrid antenna

* Corresponding author
Abstract : In the frame of the EFDA task HCD-08-03-01, a 5 GHz Lower Hybrid system which should be able to deliver 20 MW CW on ITER and sustain the expected high heat fluxes has been reviewed. The design and overall dimensions of the key RF elements of the launcher and its subsystem has been updated from the 2001 design in collaboration with ITER organization. Modeling of the LH wave propagation and absorption into the plasma shows that the optimal parallel index must be chosen between 1.9 and 2.0 for the ITER steady-state scenario. The present study has been made with $n_{||}$ = 2.0 but can be adapted for $n_{||}$ = 1.9. Individual components have been studied separately giving confidence on the global RF design of the whole antenna.
