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： The present invention relates to a high-voltage x-ray tube (R) with an inner vacuum chamber (11) in which lie, oriented opposite one another, a cathode (8) held at a negative high voltage during operating conditions and an anode (2) held at a positive high voltage during operating conditions, wherein the anode (2) is affixed to an anode isolation element (3a) such that the anode isolation element (3a) has a cylindrical form or a form tapering toward the anode (2) and comprises an opening (5a) to receive a high-voltage plug (12) and has a conductor structure (6/7) via which a coolant can be supplied to the anode (2). This coolant can be, in particular, an insulating oil or another electrically nonconductive liquid. The conductor structure (6/7) can, for example, be integrated completely into the interior of the anode isolation element (3a) but can also be integrated into the surface of the high-voltage plug (12). In another possible solution, the conductor structure (6/7) is integrated into an intermediate element (13) which lies between the anode isolation element (3a) and the high-voltage plug (12).

摘要： A supporting member supports an anode target at one end thereof and is provided with an attachment portion around the outer circumference of the other end. The attachment portion is attached to the inner circumferential surface of the cylindrical portion of the second vacuum envelope member so that the heat conductivity from the supporting member to the second vacuum envelope member can be improved by means of the attachment portion. A terminal is provided at the end surface portion on the side of the other end of the second vacuum envelope member for applying a voltage to the anode target. The terminal is positioned away from the attachment portion so that the temperature of the insulating material that insulates the terminal can be kept low and the insulating characteristics can be ensured over the long term.

摘要： The present invention relates to an X-ray source for the generation of fluorescent X-rays comprising an electron source (1) for the emission of electrons (6) and a target which emits X-rays (10) in response to the incidence of the electrons (6), said target comprising a ring-shaped primary target (2) for the emission of primary X-rays (9) in response to the incidence of the electrons (6) and a secondary target (3) for the emission of fluorescent X-rays (10) in response to the incidence of the primary X-rays (9). To obtain an enhanced radiance, it is proposed that the primary target (2) comprises a liquid metal channel (8) arranged in radial direction relative to a central axis (4), and that a liquid metal circulates in the liquid metal channel (8) during operation of the X-ray source in radial direction from an inner side (13) to an outer side (14) of said ring-shaped primary target (2).

摘要： This invention relates to a microfocus X-ray tube having a heat-dissipation solid formed on the target adhesively. Specifically, the heat-dissipation solid defining an opening is formed on the target surface irradiated with an electron beam. Heat generated adjacent the target surface by impingement of an electron beam having passed through the opening is promptly distributed by heat conduction through the surface solid. The heat-dissipation solid contributes to lowering of a surface temperature of the target layer with which the electron beam collides, and a reduction of evaporation of a material forming the target, thereby extending an X-ray generating time.

摘要： An x-ray source assembly and method of operation are provided having enhanced output stability. The assembly includes an anode having a source spot upon which electrons impinge and a control system for controlling position of the anode source spot relative to an output structure. The control system can maintain the anode source spot location relative to the output structure notwithstanding a change in one or more operating conditions of the x-ray source assembly. One aspect of the disclosed invention is most amenable to the analysis of sulfur in petroleum-based fuels.
