28.3.1979 1 PHN. 9222. ABSTRACT: "Cathode-ray tube". A cathode-ray tube having an electron gun to generate an electron beam and a focusing lens to focus the electron beam on a target. The anode of the electron gun forms part of the focusing lens and has a very small aperture to limit the electron beam. In order to prevent positive ions formed in the tube from poison- ing the cathode the potential of the anode is at most 75 volts relative to the cathode potential and the dis- tance from the centre of the focusing lens and the aper- ture in the anode is at least equal to 1.5 times the largest dimension of the anode in a cross-section at right angles to the axis.
