Abstract

L'invention concerne un tube à ondes progressives comportant un canon à électrons fournissant un faisceaux d'électrons dans l'axe ZZ' d'une hélice (20) du tube, une onde hyperfréquences injectée par une extrémité d'entrée (22) de l'hélice et se propageant le long de cette hélice étant couplée électromagnétiquement avec le faisceau d'électrons. Le diamètre (d) de l'hélice au niveau de l'autre extrémité de sortie (24) de l'hélice est inférieur au diamètre de la partie de l'hélice entre l'extrémité d'entrée (22) de l'hélice et cet autre extrémité de sortie (24) de l'hélice de façon à augmenter le couplage entre l'onde hyperfréquence et le faisceau d'électrons au niveau cette autre extrémité de sortie de l'hélice.The invention relates to a traveling wave tube comprising an electron gun supplying an electron beam in the ZZ 'axis of a helix (20) of the tube, a microwave wave injected through an input end (22) of the tube. the helix and propagating along this helix being electromagnetically coupled with the electron beam. The diameter (d) of the propeller at the other output end (24) of the propeller is less than the diameter of the part of the propeller between the input end (22) of the propeller and this other output end (24) of the helix so as to increase the coupling between the microwave wave and the electron beam at this other output end of the helix.
