Abstract
An x-ray tube has an evacuated housing rotatable around a rotational axis with a cathode and an anode being rigidly mounted in the housing so as to rotate therewith. The cathode emits electrons which are accelerated with an electrical field so as to strike the anode. An electromagnetic system for deflecting and focusing the electron beam has a number of current-permeated coil elements, whereby the coil elements are arranged a common carrier that at least partially surrounds the housing.
