A cathode ray tube is described having at least one electron gun including a cathode, a control grid, and a focusing unit, and a strip made of electrically conductive material applied to the cathode ray tube in parallel to the outer coating of the tube and connected to ground potential. Means and measures are provided to eliminate harmful effects of high-voltage sparkovers. The cathode ray tube may be is used, for example, in monitors.
