Abstract
An apparatus, which generates ionizing radiation, includes a column having a sandwich-like configuration. The column includes one or more tubes and a layer of a cured epoxy-resin mixture containing a heavy metal. The layer of epoxy-resin mixture adheres to the tube or, if the several tubes are provided, the layer adheres to the tubes. In this way, the layer defines a unit with the tube or tubes. The configuration of the apparatus provides a configuration, which is tight against exiting X-ray radiation, also in regions of breakouts and tube transitions.
