Abstract
561,199. Electron oscillators. AKT.- GES. BROWN, BOVERI, & CIE. June 11, 1941, No. 7404. Convention date, Feb. 28, 1940. [Classes 39 (i) and 40 (iii)] In a velocity modulation tube both the input modulator and the output inductor are pairs of electrodes with attached antennµ so situated within the same wave guide that the amplitude of the high-frequency voltage at the modulator is smaller than that at the inductor. In the form shown, an electron stream from gun 2, 3, 4, Fig. 1, passes through modulator grids 6, 7 and after bunching delivers energy to inductor grids 9, 10, finally falling on collector 11. Grids 6, 7, 9, 10 are supported from the walls of the wave guide 32 by narrow antennµ 14 ... 17. Waves emitted by antennµ 14, 15 towards end wall 4 are reflected to form standing waves, from which antennµ 16, 17 pick up a reduced feed-back voltage. The vacuum space is closed by a dielectric disc 35 at a distance from grids 9, 10 equal to their distance from the end wall 4, so as to minimize dielectric and reflection losses. The waves generated in the guide may be radiated into free space from a horn, or the further end may be metallically closed and a voltage picked up by an antenna for transmission through a coaxial line. When the wave is of H1 type, antennae 14, 15 are collinear and parallel to antennµ 16, 17 ; the collector 11 is supported by rods at right angles to these to eliminate pick-up from the electric field. This type has a high transverse electric field in the centre so that undesirable deflection of the beam may occur. This is avoided by using H2 or higher type waves in which the central field is small. With an H2 type the lines of electric force are as shown in Fig. 9 and the grids are supported by double antennae 14, 14<1>, Fig. 7, and 15, 15<1> at right angles, the collector support rods being placed at 45 degrees to these. The antennµ may carry cooling pipes for the grids, or the whole of the guide 32 may be cooled by liquid.
