Abstract
Abstract An electronic device wherein an interaction of an electron beam and a high frequency wave propagating through a delay line is achieved. The electron beam is made to strike substantially the whole length of said delay line simultaneously, which line upon this strike emits secondary electrons which are collected either by a grid parallel to the delay line or by the surface itself of said line. Such devices constituting either electronic amplifier or storage tubes.
