Abstract
The invention relates to a cathode ray tube comprising means ( ) for generating an electron beam ( ), means ( ) for deflecting the electron beam, and a coil ( ′) for influencing a deflection of the electron beam ( ). The coil ( ′) comprises an electrically conductive coil holder ( ) and coil windings ( ) having an electrically conductive outer layer ( ). The electrically conductive layer ( ) of the coil wires ( ) and the coil holder ( ) cooperate with each other so as to form a conductive path A between successive coil windings ( ). Due to the outer layer ( ) of the wires and the conductive coil holder ( ) an electrical path A between successive windings ( ) is created that provides damping and by which ringing is suppressed.
