ABSTRACT:
An electron beam generator with a linear cathode which has at least one end clamped to enable the cathode to move longitudinally. A beam forming electrode is at the same potential as the cathode and has an exit opening for the electron beam. The beam-forming electrode is provided with connection means to supply beam and heater voltage to the cathode. The clamps used to clamp the cathode, are connection contacts for the ends of the cathode and are outside of the contact points in the emission area of the cathode.
