Popis: Additional RF heating in the ion cyclotron range of frequencies is planned to be applied to the ASDEX tokamak and to the W VII-A and AS stellarators. To meet the physics requirements of these experiments, an RF power of 3 MW for 10 s is necessary at frequencies between 30 and 115 MHz. This power will be produced by one common generator system and transported to the experiments by long coaxial transmission lines. The ICRH system is described including the antenna design for ASDEX and W VII-A, the RF generator, the transmission lines and the tuning systems. Based on antenna calculations and model measurements the layout of the antennas and of the tuning systems has been optimized in order to reduce the electrical stress at critical points and to provide a maximum of radiated power within given geometrical limitations.
