Iter Icrf Antenna Optimization And Broad-Banding Validation By Use Of A Reduced-Scale Mock-Up

The ITER ICRF antenna has been optimized by making use of numerical tools. Flexible reduced-scale mock-ups have been constructed in order to validate the results of the optimization. The different mock-ups and their purpose are briefly described. First measurements are given, including the confirmation of the broad-banding effect of the service stub. The comparison of the measurements with results of numerical simulations is the subject of a companion paper. The measurements and the response of the system in function of frequency are interpreted in the light of transmission line models.
