Abstract
The disclosure describes an electron gun having cathode support structure which comprises an eyelet that surrounds a cathode and is welded to the cathode, and a metal platesubstantially parallel to the longitudinal axis of the gun. The metal plate has a central partfolded so as to partially surround the eyelet and two side armsextending an each side of the central part and connected thereto by a region. The region has, in the direction of the longitudinal axis, a width which is greater than the width of the side arms in the same direction, thereby making it possible to use the same support for the side and central cathodes of a three-beam gun.
