Abstract: An anticathode is repeatedly moved along a rotating axis of the anticathode while the anticathode is rotated around the rotating axis. Then, energy beams are irradiated onto a surface portion of the anticathode which is located against a centrifugal force generated from the rotation of the anticathode to partially melt the surface portion through the heating said surface portion near the melting point of the anticathode or over the melting point of the anticathode, thereby generating an X-ray from the rotating anticathode.

Abstract: An X-ray tube including an envelope enclosing a flat-edged anode disc rotatable and axially reciprocable and further enclosing an electron beam source for projecting electrons along a beam axis toward the edge of the anode disc. The beam source is disposed to direct its beam at an acute angle of incidence to the edge of the anode disc and produce X-rays which are transmitted through a window in the envelope.

Abstract: A sealed-off X-ray tube having a convex target surface facing an electron beam source and carried by a rigid support mounted for rotary pivotal motion about a fixed pivot point. A bellows is sealed vacuum tight to the target and to the wall of the tube around the pivot point so that the target, the bellows, and the envelope of the tube form a closed surface. Conduits extend through the pivotal bearing to direct the flow of cooling fluid against the back surface of the target and carry the fluid away. The target surface is spherically convex with a center of curvature at the pivot point. The axis of the target precesses about the axis of the tube but the target does not rotate on its own axis. The target may be moved manually or by motor and with a linear, circular or spiral motion. Because of the curvature of the target, the electron optical forces are substantially unaffected by the precessing motion, and virtually constant X-ray beams radiate through windows of the tube.
