First Results of Automatic Matching System on Tore Supra ICRH Antennas; Fast Matching Network for ICRH Systems**SPINNER Gmbh Erzgiessereistrasse 33 8000Munich 2 RFA

Tore Supra ICRH Resonant Double Loop antennas are now equipped with an automatic matching system based on internal capacitors active control. First results on power experiments are exposed. For future experiments and fast transients, the principle of a fast matching network for ICRH systems has been developed and first tests on a laboratory mock-up have been performed.
