As a result, effective interaction of the wave with the electron beam can be achieved over a wide frequency band. Fonctionnant sur le même principe que les tubes classiques, ces prototypes ont été construits avec un émetteur d'électrons formé de petites pointes utilisant des nanotubes , et en gravant les électrodes comme des petites plaques rabattables par une technique similaire à celle qui est utilisée pour créer les miroirs microscopiques utilisés par la technique Digital Light Processing qui sont maintenues debout par un champ magnétique. The rf input and output are coupled onto and removed from the helix by waveguide directional. La cathode est la source des électrons qui constituent le faisceau électronique dans tous les tubes hyperfréquence. Since the electron beam can be accelerated only to velocities that are.

Les tubes les plus performants emploient même une double variation de la périodicité: d'abord une augmentation du pas donc de la vitesse de l'onde vue par les électrons pour améliorer la formation des paquets d'électrons, suivie d'une réduction du pas pour un freinage plus efficace. Silicon controlled rectifier SCR. As power level increases, the wire can overheat and cause the helix geometry to warp. C'est le tube le plus simple, utilisé comme redresseur.
