THE ASDEX ICRF ANTENNAE IN THEIR UNCOOLED AND COOLED VERSIONS
In a first phase the two ICRF antennae in ASDEX were uncooled. They have operated for pulse length up to 1 s and have achieved their design power level of 1.5 MW each. The paper summarizes the design principles and the characteristics of the antenna. It further reports on some interesting points concerning their manufacturing, and highlights what we have learned from the first phase operation. In order to be able to operate with increased heating powers and pulse lengths most components inside the ASDEX vessel and the ASDEX ICRF antennae have to be cooled. For the antennae of this second phase, we present the underlying design criteria, the results of the thermal and mechanical calculations and the various manufacturing steps. First tests on the thermal loading capabilities of the screen are included.
