10.2.1979 1 PHN 9194 ABSTRACT A diode gun for a camera tube consisting of an anode and a cathode assembled in a cathode supporting bush can very readily be adjusted if the cathode suppor- ting bush and the anode in the non-connected condition are movable radially with respect to each other, the emissive cathode surface and the part of the anode extending per- pendicularly to the axis remaining accurately parallel to each other. As a result of this it is possible to cause the central path of the generated electron beam and the gun axis to coincide so that extra correction coils for aligning the electron beam may be omitted.
