Paper Abstract

Frequency agile sources for future electron cyclotron wave (ECW) systems require broadband windows that aresuitable for high-power transmission (> 0.5 MW) in the millimeter wave range. While the relative bandwidths of single-disk ordouble-disk windows used in conventional monofrequent systems are of the order of 1 %, the future systems require forbandwidths of 10 % or even more (e.g. > 60 % for the FOM-Fusion-FEM 1). A description of the different window typesunder consideration and first results of a development of suitable windows have been reported in 2. This paper presents animproved test apparatus as well as our latest experimental and theoretical results about broadband windows.
