Abstract

944,024. Travelling wave tubes. STANDARD TELEPHONES & CABLES Ltd. Dec. 22, 1960 [Dec 30., 1959], No. 44128/60. Heading H1D. A travelling wave tube has a slow wave structure in the form of a bifilar or multifilar helix whose windings are insulated from one another and arranged in such manner that an electron beam projected along the axis of the helix may be electrostatically focused by the application of different polarising potentials to the respective windings, the travelling wave tube including insulating support means disposed about the helix, each turn of each of the windings being supported at three points spaced apart around its circumference, corresponding points of support of two consecutive turns of a winding being joined by a continuous insulating surface, which the intervening turn of the other winding, or of each of the other windings, respectively, is spaced from the surface by a radial gap. Thedevice may comprise, Fig. 1A, six insulating support rods 21-26 of which three contact one helix and the other three are spaced from the helix by flats 27, 31, 32 formed on the helix by machining or grinding. For the other helix the contacting and spacing is reversed. Alternatively, a glass or ceramic clamping cylinder 45, Fig. 4, has six interior radial projections 46, whilst in Fig. 5 (not shown) projections on the helices contact the inner surface of-the cylinder. In a further embodiment, Fig. 6, the support rods 61 are alternately notched at E, F.
