  • Electron gun having electrically isolated and adjustable cathode
    Patent number: 5686785
    Abstract: An electron gun for producing a beam of electrons has an elongated, linear thermionic cathode and a focusing electrode. The opposite ends of the cathode are engaged by adjustable holders which enable the spatial separation between the cathode and focusing electrode to be easily varied. The focusing electrode is electrically isolated from the cathode whereby fine tuning of the electron beam may be accomplished by varying the potential difference between the focusing electrode and cathode.
