Abstract

A scaled mock-up (1/4) of the proposed W7-X ICRF antenna has been constructed and placed in front of dielectric dummy loads. It allows comparing measured and predicted coupling performances and hence validating the electrical design of the antenna. High dielectric constant materials are needed for the dummy load to mimic the plasma. Salted water and a mix of the ferroelectric BaTiO₃ and salted water are used. The measurements are compared with the expectations of 3 codes: ANTITER II, MWS and TOPICA. The best agreement is obtained with the BaTiO₃ load for all phasings.
