Claim 1
Independent Claim
112 words
An X-ray tube comprising an evacuated envelope, a plurality of electrodes within said envelope, a deformable rigid intermediate member connecting one of said electrodes to said envelope in a vacuum tight manner for laterally moving one electrode relative to the other, said deformable rigid intermediate member comprising a sleeve supporting the one electrode, a cup-shaped part secured to said envelope and sleeve, said cup-shaped part having a disc-shaped bottom arranged at right angles to said sleeve, and a plate having at least three relatively shifted tapped holes for receiving screws to be tightened against said disc-shaped bottom, and means for deforming said intermediate member to vary the position of the one electrode.
