Abstract: An X-ray tube has at least one grid electrode arranged between an anode electrode and a cathode electrode. Via a focusing unit, an electron flow from the cathode electrode to the anode electrode is focused in that the focusing unit supplies the grid electrode with a first electric grid potential. The focusing unit is supplied with electrical energy in an electrically isolated manner via an energy converter. The first electric grid potential is provided via an adjustable voltage divider, and the adjustable voltage divider is adjusted via a control circuit of the focusing unit in that the control circuit is supplied with an electrically isolated control signal of a control unit. The control signal depends on a value for the first electric grid potential.
