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.
