X-Ray apparatus

An X-ray apparatus comprising:

• a casing filled with an insulating gas,
• a high voltage transformer in said casing,
• an X-ray tube mounted to said casing within said casing and connected to said transformer,
• an X-ray shielding member attached to the wall of said X-ray tube and defining a window through which the X-rays radially emitted by said X-ray tube are released in a predetermined direction,
• means defining an X-ray path through which said X-rays released through said window of said X-ray shielding member are directed so as not to be radiated on said insulating gas,
• said insulating gas surrounding and insulating said high voltage transformer and said X-ray tube,
• said X-ray path defining means preventing ionization of said insulating gas by preventing X-rays emitted through said window from impinging on said insulating gas, and
• said high voltage transformer comprising a high tension coil wound in an outwardly stepped configuration toward each end thereof, insulating paper exposed on the outer surface of said coil and defining a stepped surface configuration, and a plurality of electrodes each having a length short of a full turn about said coil and wound about one stepped portion of said insulating paper, said electrodes having an equal potential to said coil.
