“…6b. A value of K D ≈ 200 (as studied in references [12,13]), still close to K Dmax , would be appropriate for all phasing conditions of ITER (see Fig. 3).…”

“…5b require the use of a large range of dielectric constant value. The use of ferroelectric and meta-materials is presently studied for this purpose [12,13]. A multilayer dielectric profile can replace the continuous profile but the number of layers has to be chosen as large as possible to avoid strong resonances and surface wave effects on the power spectrum and coupling value.…”

To support the design of ITER ion-cyclotron range of frequency heating system and to mitigate risks of operation in ITER, CEA has initiated an ambitious Research & Development program accompanied by experiments on Tore Supra or test bed facility together with a significant modeling effort. The paper summarizes the recent results in the following area:• Comprehensive characterization of a new Faraday screen concept tested on Tore Supra antenna. RF sheath rectification is now better understood: a new model has been developed and applied to ITER. • Full wave modeling of ITER ICRH heating and current drive scenarios with EVE code. With 20MW of power, a current of ±400kA could be driven on axis in the DT scenario. • First operation of CW test bed facility, TITAN, designed for ITER ICRH components testing and could host up to a quarter of an ITER antenna. • R&D of high permittivity materials to improve load of test facilities to mimic ITER plasma conditions.
