INTERRDIGITAL SLOW WAVE CIRCUIT FOR ELECTRONIC TUBE

摘要

An interdigital delay line for crossed field tubes has vanes extending from their interaction faces to a back wall. One end of each vane extends to the end of the face. The other end is cut out behind the interaction face leaving the face projecting. The interaction impedance is almost as high as that of a line with fingers supported by stubs at their centers, while the thermal dissipation is higher, approaching that of a line with vanes extending over the entire length of the fingers.
