ABSTRACT:
A coupled cavity traveling wave tube is disclosed which includes a plurality of pole piece members and hollow spacer members which are alternately arrayed to define a plurality of cavities. The pole piece members each has a central aperture and a coupling slot through which microwave energy is coupled between adjacent cavities. The tube includes a plurality of first loss elements each of which is positioned in both of two respective adjacent cavities, with each of the first loss elements having its first end in contact with the front face of a respective one of the alternate pole piece members, its central portion pass through an aperture in the next intervening pole piece member in which it is coupled to the coupling slot in that pole piece member, and its second end in contact with the rear face of the next alternate pole piece member. The tube further includes a plurality of second loss elements each of which is positioned in both of two respective adjacent cavities, with each of the second loss elements having its first end in contact with the front face of a respective one of the intervening pole piece members, its central portion pass through an aperture in the next alternate pole piece member in which it is coupled to the coupling slot in that pole piece member, and its second end in contact with the rear face of the next intervening pole piece member.
