摘要： A method for generating X-rays in an X-ray tube, comprises the steps of: rotating an X-ray target of a rotating anode, the X-ray target having a metal coated layer thereon; applying electron beams emitted from a cathode onto the metal coated layer of the X-ray target; and offsetting thermal deformation of the X-ray target due to the application of the electron beams by deformation of the X-ray target due to centrifugal force, thereby maintaining a position of the X-ray target in a direction of the application of the electron beams, at a room temperature of the X-ray target, thus generating the X-rays.

摘要： An X-ray target having a graphite body and an X-ray generating metal coating layer, in that a metal interlayer which is non-reactive with graphite and which has a coefficient of thermal expansion substantially equal to those of the graphite and the X-ray generating metal coating layer is formed at the boundary between the graphite body and the X-ray generating metal coating layer, and that the interlayer is caused to percolate into the graphite body. Desirably, the interlayer includes a part percolating into the graphite body over a depth of at least 10 .mu.m. The X-ray target can be manufactured in such a way that the surface of the graphite body is coated with the metal interlayer by subjecting the surface to chemical vapor deposition under a normal pressure or under a pressure near the normal pressure, and that the metal interlayer is thereafter coated with an X-ray generating metal by an expedient such as chemical vapor deposition, sputtering or thermal spraying. Owing to the percolation of the metal interlayer into the graphite body, the contact area of the two increases conspicuously, and heat having developed in the X-ray generating metal coating layer is quickly transmitted to the graphite body.

摘要： At least one permanent magnet and a pole piece having a projection is contained in an evacuated envelope formed by an anode cylinder and yokes on the opposite ends thereof. The permanent magnet and the pole piece is clamped between one yoke and a holder secured to the inner wall of the anode cylinder. The holder is provided with an opening a little smaller than the outer diameter of the projection and the projection is force-fitted into the opening to project into an interaction space defined between anode vanes and the cathode electrode.
