Abstract
Since ICRH antennas and their coaxial feeding lines are necessarily va cuum insulated, their RF electric strength depends mainly on the resid ual gas pressure, which can be severely impeded during high power RF a pplication. This interaction between RF, vacuum and electric strength and the consequences on design and operation are discussed in general and in the case of ICRH at ASDEX Upgrade, whose feeding design is desc ribed in detail.
