ABSTRACT:
An X-ray tube has a vacuum housing that accepts a cathode and an anode and that is provided with an electrically conductive beam exit window. During operation of the X-ray tube, the beam exit window lies at a negative potential and is electrically conductively connected via a resistance to a potential that is positive relative to the negative potential, this resistance being dimensioned such that, during operation of the X-ray tube, the difference in potential between the negative potential of the beam exit window and the positive potential lies on the order of magnitude of a few kilovolts.
