Abstract

The ITER-like ICRF antenna for JET aims at validating novel antenna design principles in conditions as relevant as possible to ITER by coupling about 7.2 MW to an ELMy H-mode plasma on JET in the frequency range from 30 to 55 MHz. The power density, about 8 MW/m2, for a given maximum voltage in the circuit is maximized using poloidally short straps and the resilience to fast varying RF loads by matching pairs of straps by a so-called conjugate-T. The paper reports the main characteristics of the final design as well as the main challenges encountered during the design and testing phase of the key components. © 2005 Elsevier B.V.
