    摘要： The present invention relates to a slow wave structure (1) for transmitting an electromagnetic wave in a travelling wave tube (2), wherein the slow wave structure (1) comprises an electrical conductor (10) formed along a helix, wherein the helix twists around a longitudinal axis (11). In order to provide a slow wave structure and a traveling wave tube amplifier facilitating a simplified amplification of high frequency electromagnetic waves, the electrical conductor (10) comprises at least one coupling section (12), wherein the coupling section (12) is formed in order to generate a non-zero axial electric field outside a space confined by an envelope of the helix of the electrical conductor (10) in a direction parallel to the longitudinal axis (11), when during operation of the slow wave structure (1), the electromagnetic wave is transmitted along the electrical conductor (10), wherein the axial electric field is generated between two ends of the coupling section (20, 20'), wherein the ends of the coupling section (20, 20') are distanced from each other in a direction parallel to the longitudinal axis (11).

    摘要： An electron beam tube includes a unitary metal cylinder 11 and a plurality of transverse walls 12 to 19 located within it which define resonant cavities 20, 21, 22 and 23. As the cylinder 11 is in one piece vacuum joints 31 and 32 are only required at the ends of the structure. Drift spaces between the resonant cavities are enclosed within drift tubes 27, 28 and 29. The inner diameter of the tube 11 is stepped to facilitate assembly and accuracy of the structure. In use, an electron beam is directed along the longitudinal axis X-X and interacts with applied r.f. energy to produce amplification of the r.f. signal.

    摘要： A magnetron comprises an anode (2) having vaner (3a, 3b) which define a plurality of cavities. A dielectric resonator (7) is located such that it is in communication with at least one of the vanes (3a, 3b). In use, the dielectric resonator (7) at least partially absorbs spurious radiation generated in a predetermined mode of operation of the magnetron, such as the π - 1 mode. Power generated in the π -1 mode, if transmitted, may interfere with other electronic devices. The resonator (7) may be of ceramics material, such as alumina.
