Abstract: An X-ray source has an evacuated housing containing an interior space and a housing projection having a projection interior communicating with the interior space. A cathode is mounted in the projection interior and an anode is mounted in the interior space. Two tubes proceed substantially parallel to each other through the projection and are sealed relative to the projection interior, the two tubes being disposed on opposite sides of an electron beam that proceeds from the cathode to the anode during operation of the X-ray source. An electromagnetic electron beam deflector has a U-shape with two legs that are respectively disposed in the tubes. The electron beam deflector is controllable to generate a magnetic field that deflects the electron beam to set a position of the focus on the anode.

Abstract: A method for manufacturing x-ray tube parts wherein metallic pieces are explosively bonded together to establish a high strength, stable union between them. The x-ray tube parts may then be milled from the bonded metallic pieces. The explosion bonding process creates only discrete intermetallic components in the joint region instead of a continuous, weakening intermetallic layer common in brazed joints. An explosion bond joint is characterized by a wavelike interface, thereby increasing surface area over which the components are bonded and further increasing bond integrity. Rotor sleeves and other tube components may be manufactured using this method.

Abstract: An x-ray imaging apparatus having an anode stem assembly with explosion-bonded joints is provided. Explosion-bonding the components of an anode stem assembly to one another provides a hermetic seal with increased reliability as well as reducing the anode stem's susceptibility to thermal and/or mechanical induced fracture. By eliminating the need for brazing and/or welding material within the anode stem, the present invention also provides an anode stem with increased heat transfer capabilities. Further, providing explosion-bonded joints creates a simple joint microstructure absent any voids and temperature-induced phases not previously present in the anode stem materials.

Abstract: A joining method designed to minimize the temperature needed to obtain a high strength braze joint between a molybdenum alloy substrate and a graphite disk used in a rotating anode X-ray tube target used for computed tomography applications. The method consists of two separate brazing operations. The first brazing operation joins a thin molybdenum sheet to the graphite disk using a pure metal braze to form a plated graphite subassembly. The second brazing operation joins the plated graphite subassembly to the molybdenum alloy substrate using a highly specialized braze alloy having a melt temperature below the recrystallization temperature of said molybdenum alloy substrate and a remelt temperature after brazing above the recrystallization temperature of said molybdenum alloy substrate. This two step brazing reduces the probability of fracture in the graphite by maintaining the elevated temperature yield strength normally developed in forged molybdenum alloy substrates by avoiding the deleterious yield strength reduction associated with recrystallization of the molybdenum alloy substrate.

Abstract: Provided are a high-quality and high-reliability rotary anode target for X-ray tubes, of which the mechanical strength at high temperatures is increased and which is applicable not only to low-speed rotation (at least 3,000 rpm) but also even to high-speed rotation at high temperatures, and also a method for producing it. The rotary anode has a two-layered structure to be formed by laminating an Mo alloy substrate that comprises from 0.2% by weight to 1.5% by weight of TiC with the balance of substantially Mo, and an X-ray generating layer of a W—Re alloy that overlies the substrate.
