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.
Claims13
An X-ray tube comprising:
- a vacuum housing;
- a cathode arrangement and an anode arrangement disposed in said vacuum housing;
- a high-voltage terminal electrically connected to said anode arrangement and mounted on said vacuum housing so as to be accessible from an exterior of said vacuum housing;
- and
- an electrical damping resistor disposed inside said vacuum housing and connected between said high-voltage terminal and said anode arrangement and through which a tube current flows when a high-voltage is supplied to said high-voltage terminal.
