Abstract: The x-ray target assemblies have an oxide dispersion strengthened (ODS) refractory metal alloy substrate that is bonded to a carbon-containing heat sink. The x-ray target assemblies have excellent bonding between the substrate and the heat sink. The improved bonding is achieved by placing an oxide-free barrier layer between the ODS metal substrate and the heat sink. The oxide-free barrier layer minimizes or eliminates chemical reactions that would otherwise be possible between the dispersed oxides and the carbon-based heat sink during the manufacturing process. Preventing these undesired reactions while manufacturing the x-ray target assembly yields a device with improved bonding between the heat sink and the substrate, compared to devices manufactured without the barrier layer.

Abstract: In an X-ray tube, a rotary anode formed into a hollow disk-like shape is fixedly supported by a rotating body formed into a hollow cylindrical shape. A fixed shaft has fixed ends, columnar bearing portions and a disk part, and a flow path of a cooling medium formed along a central axis thereof. The bearing portions are inserted into the rotating body with a first gap between the columnar bearing portion and the rotating body, so that the rotating body is rotatably supported. The disk part is arranged in the rotary anode with a second gap between the disk part and the rotary anode. The first and second gaps are filled with a lubricant, bearing grooves are formed in the bearing portion, thereby forming dynamic pressure bearings, and a center of gravity of the rotary anode is arranged between the first and second dynamic pressure bearings.

Abstract: The invention relates to a device for generating X-rays (41). The device comprises a source (5) for generating an electron beam (35), and a carrier (7) which is rotatable about an axis of rotation (15) and which is provided with a material (9) which generates the X-rays as a result of the incidence of the electron beam thereon. The device further comprises a heat absorbing member (45) which is arranged between the source and the carrier to catch electrons, which are scattered back from an impingement position (39) of the electron beam on the carrier, and to absorb a portion of the radiant heat generated by the carrier when heated during operation. The heat absorbing member is in thermal connection with a cooling system (51) of the device. According to the invention, the thermal connection between the heat absorbing member (45) and the cooling system (51) comprises a thermal barrier (57) which limits a rate of heat transfer (( ) occurring via the thermal connection per unit of temperature difference between the heat absorbing member and the cooling system. In a particular embodiment, said thermal barrier comprises an annular mounting member (57) having a limited dimension (hB), by means of which the heat absorbing member is mounted in the device. As a result of said thermal barrier, the heat absorbed by the heat absorbing member is gradually transferred to the cooling system, so that thermal peak loads on the cooling system and problems like boiling of the cooling liquid are avoided. In addition, relatively high temperatures of the heat absorbing member are allowed, so that the mass and volume of the heat absorbing member, which are necessary to provide the heat absorbing member with a sufficiently large heat absorbing capacity, are considerably reduced.
