ABSTRACT:
A travelling wave tube of the kind having clover leaf cavities is provided with a periodic permanent magnetic structure, in which the magnetic material is located within noses projecting into the cavity space. A barrier between the magnetic material and the cavity space defines an evacuated envelope. Because the magnetic material is within the volume swept out by the cavity dimensions, it is positioned very close to the electron beam path.
