Abstract: An X-ray tube having at least one electrode connected with the tube envelope so as to provide for alignment of the electrodes. This is implemented by supporting the electrode upon an intermediate member which can be deformed to vary the position of the electrode.

Abstract: The invention relates to an X-ray tube in which the anode and the cathode are accommodated in two parallel adjacent envelopes which are interconnected by a tubular member through which the electron beam passes. At high voltage (300 kV and higher) the direction of the electron beam and the direction of the maximum of the X-rays are inclined at an obtuse angle to one another. Thus the electrons impinge on the target nearly at grazing incidence. Even at slight deviation of the relative positions of the anode and cathode envelopes from the prescribed positions the focal spot is greatly shifted. According to the invention the two envelopes are relatively movable, causing substantially a deformation of the coupling member only which is capable of deformation owing to the use of an appropriate construction and/or a suitable material.
