Abstract: An x-ray image intensifier has a housing, an input screen, an output screen, and a number of electrodes for the electron optics, the housing including a number of joined parts and at least one of those parts consisting of electrically insulating material. The part or parts of the housing consisting of insulating material have seating surfaces to which parts, such as the electrodes, are secured by shrinking.

Abstract: An x-ray image intensifier having a tube bulb and an output window being mounted in a metal frame. The frame is inserted into the tube bulb and attached to the tube bulb in a region of the output window characterized by the output window being a glass window having a luminophor layer applied thereto, the output window being connected to the frame by only a single metal solder connection of soft solder so that the pane having the luminophor layer can be soldered to the frame without damaging the luminophor layer. Preferably, a peripheral edge of the window pane is free of the luminophor layer, and this peripheral edge has at least one adhesive layer deposited at the location for the solder connection.
