Abstract

925,551. Velocity modulated tubes. RADIO CORPORATION OF AMERICA. Nov. 20, 1959 [Dec. 16, 1958], No. 39543/59. Class 39 (1). A periodic electrostatic focusing electrode system for a travelling- wave tube or as shown, for a klystron, comprises a plurality of spaced high potential electrodes 53 with intervening groups of electrodes which are graded in potential, Fig. 5 (not shown), or, as shown, intervening double conical electrodes 51 in order to produce at the boundary of the beam a parabolic potential variation in each half-period which approximates in form to the variationthat ideally exists in an electron flow of infinite width between a pair of grids at maximum and minimum potentials. The electron gun can be of the convergent flow-type as shown, or of the parallel flow type, Fig. 11 (not shown). Electrodes 51, 53 may have central grids. End discs 59 on electrodes 51 form R.F. chokes with the electrodes 53 and flanges 58 on ceramic envelope discs 55. The resonators 27, 31 have R.F. chokes formed by ceramic rings 61 and flanged discs 63, 65 or, alternatively, circumferential rings, Fig. 11 (not shown).
