    Abstract: An electron-beam apparatus, for example, for the electron-beam welding of metal or other workpieces comprises an evacuatable chamber and a duct connecting this chamber with a suction source, e.g. a vacuum pump. To prevent the passage of secondary emissions, e.g. X-rays, through this duct, the invention provides a plurality of baffle members in spaced relation along the duct and swingable into a position generally parallel to the duct axis during evacuation of the chamber to prevent obstruction of the fluid flow thereto. Subsequent to evacuation and during electronbeam welding, however, the baffles, shutters or shielding members extend transversely to the axis to intercept the X-rays.

    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.
