Abstract
An X-ray tube has a vacuum housing, on which is provided a high-voltage terminal connected to the anode. An electrical damping resistor, through which the tube current flows and which is connected between the high-voltage terminal and the anode, is arranged within the vacuum housing. This resistor can be constructed as a component through which the tube current flows, and which connects the anode plate with its mount, such as a rotor in case of a rotating anode X-ray tube. The component has a low electrical conchannelivity so that the connection of the anode plate with the mount has a resistance of at least 250 ohms and at most 15 kiloohms.
