ABSTRACT:
In an electron gun, e.g. for a cathode ray tube, an anode is supported from another anode by spacers which fit between overlapping portions of the two anodes and locate in recesses in the two overlapping portions. The spacers are typically glass balls. The invention finds especial application in mounting of a final anode whose diameter is greater than the diameter on which rods supporting the other electrodes of the gun lie.
