摘要： An x-ray tube has an anode plate connected to an anode tube that is mounted such that it can rotate around a rigid anode shaft. To improve the heat dissipation from the anode plate, a liquid for dissipation of heat to the anode shaft is accommodated in an intervening space formed between the anode shaft and the anode plate.

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.

摘要： The present specification discloses a high power continuous X-ray source having a rotating target assembly that is cooled by circulation of a liquid material in contact with the target assembly, whereby the target assembly has a front surface being impinged by electrons and a mechanism for rotating the target assembly. The cooling liquid is always in contact with at least one surface of the target for dissipating the heat generated by the energy deposited by the stream of electrons, thereby lowering the temperature of the target to allow for continuous operation.

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, 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. Also, a corresponding circulation system and an X-ray source provided with such circulation system.

摘要： A system and method are proposed for cooling the anode of an X-ray tube. A bearing shaft associated with the anode has an associated single rotating seal there around, and contains a liquid metal. A primary liquid metal flow path is used to transfer heat from the anode, and a secondary liquid metal flow path is provided to seal the single rotating seal. Accordingly, the present invention provides an effective means for containing liquid metal in the bearing shaft of an anode assembly, and using the liquid metal to cool the anode of the X-ray tube.

摘要： An anode has a base member, on which an X-ray active layer is applied. A first cooling circuit with a first cooling medium extends at least in part in the base member beneath the X-ray active layer. A second cooling circuit with a second cooling medium is arranged beneath the first cooling circuit. The anode exhibits distinctly improved thermo mechanical properties.
