Slotted waveguides and ribbon electron beams are studied as electron- beam interaction circuits instead of the usual circular-beam devices. The slotted waveguide and ribbon beam can be many wavelengths long, and therefore the effective beam cross-sectional area is greatly increased over that of the circular beam helix, coupled-cavity or kylstron tubes. This increased beam area results in more beam current, more beam power, and less stringent requirements on cathode current density and focusing fields. The slotted waveguides are made by milling either grooves or threads into a slab of metal, and are therefore rugged and self-aligning. Both theory and experiments are described.
