ABSTRACT:
An electron beam tube is described, having a flat cathode and a flat, close-spaced grid to density modulate the beam. The beam passes through an apertured anode and then through a hollow drift tube which is the central conductor of a coaxial resonator. A gap in the drift tube extracts wave energy from the density modulated beam.
The cathode-grid region is electrically isolated from the output resonator by the length of the drift tube which is cut off as a waveguide. The circuit is thus completely grounded-grid. The input resonator, a coaxial line connected across the cathode-grid space, is loaded by the input conductance, so as to reduce the gain. The invention increases the gain by introducing regeneration between the grid-anode space and the cathode-grid space. This is done by a coupled coaxial resonator system.
