Abstract :
The F.E. Tube is a three-electrode device in which a short hollow beam of electrons is modulated by varying the voltage of an electrode (gate) which surrounds the beam. An axial magnetic field prevents the beam from spreading and touching the gate Electrical characteristics are similar to those of a pentode. A very low knee voltage is possible with a tilted collector which reflects slow electrons towards the non-emitting part of the cathode.
