Abstract
An X-ray tube has a vacuum housing that contains a cathode and an anode, the housing having a radiation exit window. The radiation exit window is electrically conductive, and lies at cathode potential, and is electrically insulated against the vacuum housing, which lies at a potential that is positive in relation to the cathode potential.
