摘要： A bearing structure for an X-ray tube is provided that includes a journal bearing shaft with a radially protruding thrust bearing flange encased within a bearing housing or sleeve. The sleeve includes a thrust seal that is engaged with the sleeve in a manner to maintain coaxiality for the rotating liquid metal seal formed in the sleeve about the shaft. The shaft includes a central bore containing a cooling tube that directs coolant within the bore to maximize the heat transfer from the shaft to the coolant, allowing materials with lower thermal conductivities, such as steel, to be used to form the bearing shaft. The thrust flange on the shaft is formed with channel(s) therein that enable the coolant and/or the liquid metal to effect greater heat transfer on the components of the sleeve through the thrust flange, thereby reducing thermal deformation of the bearing components.

摘要： Closed-loop circulation for providing liquid metal to an interaction region at which an electron beam is to impact upon the liquid metal to produce X-rays is presented. In a method according to the invention, the pressure of the liquid metal is raised to at least 10 bar using a high-pressure pump. The pressurized liquid metal is then conducted to a nozzle and ejected into a vacuum chamber in the form of a spatially continuous jet. After passage through the vacuum chamber, the liquid metal is collected in a collection reservoir, and the pressure of the liquid metal is raised to an inlet pressure, e.g. using a primer pump, suitable for the inlet of the high-pressure pump. The invention also relates to a corresponding circulation system and an X-ray source provided with such circulation system.

摘要： Liquid metal containment in an x-ray tube. In one example embodiment, an x-ray tube anode assembly includes a stationary shaft terminated by a head and an anode connected to an anode hub. The anode hub is at least partially surrounding the head of the stationary shaft. The anode hub defines a hub opening through which the stationary shaft extends. The anode hub is configured to contain a volume of a liquid metal and to rotate around the stationary shaft. The anode hub also defines a catch space within the anode hub that is configured to catch the liquid metal in order to contain the liquid metal within the hub regardless of the orientation of the x-ray tube anode assembly.

摘要： A mechanism for cooling the anode of an x-ray tube using a phase change material to transfer heat away from the anode. The x-ray tube is joined to a sealed heat exchange chamber which contains a liquid metal as a liquid to vapor phase change material (L-V PCM). The back side of the anode is exposed to an interior of the heat exchange chamber, and a jet sprayer inside the heat exchange chamber sprays a liquid of the metal onto the back side of the heated anode. The L-C PCM evaporates on that surface to carry away the heat, and the vapor then condenses back into the liquid on the cool surfaces of the heat exchange chamber. The surfaces of the heat exchange chamber may be cooled by convection cooling. Optionally, pipes containing a circulating cooling fluid may be provide inside the heat exchange chamber.

摘要： An x-ray tube (10) includes an evacuated envelope (14), a cathode assembly (20) located in the evacuated envelope and a disk shaped anode assembly (18) located in the evacuated envelope in operative relationship with the cathode assembly for generating x-rays (40). The anode assembly includes an axis of rotation (26) and a target substrate (28) facing the cathode assembly. A heat pipe (33) is located within the anode assembly (18). The heat pipe is comprised of an evacuated shell (60) and is vacuum sealed at a first end (70) of the shell and at a second end (72). A material (80, 82) within the shell is a working fluid for the heat pipe at x-ray tube operating conditions. A porous wick (62) is located within the shell and the wick has a length extending from the first end (70) of the shell to the second end (72) of the shell. A shield (64) is attached to the wick to reduce working fluid loss out of the wick during x-ray tube operation.
