摘要：

Sufficient coupling of an ICRF antenna for high power experiments was obtained even for a wide gap between the separatrix and the antenna in JT-60U. The loading resistances for an out-of-phase mode are over 4 OMEGA for a gap of 13 cm between the separatrix and the Faraday shield over the wide range of electron density from 1 x 10(19) to 5.5 x 10(19) m-3. In particular, the loading resistances for an in-phase mode are about 5 OMEGA for a gap of 33 cm between the separatrix and the Faraday shield for the same plasma parameters. However, die heating response for the out-of-phase mode is much stronger than that for the in-phase mode.
