Definitions

  • the invention has for its object to obviate as far as possible this limitation in the case of ribbon-shaped beams and to keep the focal distance for all positions of the beam as constant as possible.
  • a device comprising an electric discharge tube having a ribbon-shaped beam and comprising at least a cathode, an accelerating electrode, two deflecting plates arranged opposite one another, one of which has a fixed voltage, and a collecting electrode, the deflecting plates are shaped in such a form and arranged in such a manner that in each position of the beam the variation of the spatial potential along the beam viewed from the accelerating electrode remains substantially constant in the direction of travel of the electrons.
  • the spatial potential between the plates will vary unsymmetn'cally with respect to the center, so that the, variation of the spatial potential along the beam varies strongly with the deflecting voltage. Since the second derivative of the spatial potential in accordance with the length of the beam is not equal to zero, tional lens effect is produced in the deflection space, varying for diiferent values of the deflection voltages; it is strongest for those values at which the potential of the controlling deflecting plate is lower than the potential of the other deflecting plate.
  • Fig. 2 shows a tube construction according to the invention in a diagrammatical form
  • Fig. 4 shows a further embodiment of a tube according to the invention.
  • the invention is, consequently, of importance, as for example for counter tubes, relay tubes and the like.
  • a circuit arrangement comprising an electric discharge tube; said tube comprising means for producing a ribbon-shaped electron beam including a cathode and an accelerating anode having an aperture therein through which the ribbon-shaped beam emerges, collecting means for said beam spaced from said beam-producing means, and a deflection system for said beam disposed between the accelerating anode and the collecting means, said deflection system including a pair of substantially alike, opposing deflection plates each having a first portion 10- catcd near the aperture in said accelerating anode and a second portion diverging outwardly from said aperture toward the collecting means; means applying positive potentials to said accelerating anode and collecting means to produce a potential distribution therebetween, means applying a fixed positive potential to one of said deflection plates, means applying a varying positive potential to the other of said deflecting plates tending to vary the potential distribution between the accelerating anode and collecting means and thereby vary the focussing action on the beam; and a deflecting rod disposed between the first portions of. said deflection
