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 (312). The pressurized liquid metal is then conducted to a nozzle (332) and ejected into a vacuum chamber (330) in the form of a spatially continuous jet. After passage through the vacuum chamber, the liquid metal is collected in a collection reservoir (334), and the pressure of the liquid metal is raised to an inlet pressure, e.g. using a primer pump (322), 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： An X-ray tube rotating anode (14) is cooled with a liquid metal (40) functioning as a recirculated heat exchange fluid and/or a metal film in a gap (39) between the anode (14) and a stationary structure. The liquid metal (40) is confined to the gap (39) by (a) a labyrinth (44 or 46) having a coating that is not wetted by the liquid, (b) a magnetic structure (22), or (c) a wick (38). The liquid metal (40) recirculated through the anode (14) is cooled in a heat exchanger located either outside the tube or in the tube so it is surrounded by the anode (14). The heat exchanger in the tube includes a mass of metal in thermal contact with the recirculating liquid metal and including numerous passages (36) for a cooling fluid, e.g. water. A high thermal conductivity path (26, 48, 49) is provided between an anode region (16) bombarded by electrons and a central region of the tube where heat is extracted. In one embodiment the high thermal conductivity is achieved by stacked pyrolytic structures having crystalline axes arranged so there is high heat conductivity radially of the region and lower thermal heat conductivity normal to the high heat conductivity direction.

摘要： The invention relates to an X-ray generator (100) with a compact construction produced using simple resources, suitable for emitting a very high radiation output, even over longer time periods, said generator containing: a high-emission thermal low-temperature cathode (101) for emitting an electron beam (102); a rotary anode (107) comprising an anode plate (106), said rotary anode being rotatably guided in a bearing assembly (114) about an axis of rotation (115), the bearing assembly having a liquid-metal sliding bearing (123) between a bearing part (120) connected to the rotary anode and a bearing shaft (122); an electron focussing device (108) for focussing the electron beam on a focal track (109) along a surface of the anode plate; and a condensation cooling assembly designed with a first coolant which is present between the focal track and the bearing part of the rotary anode and with a configuration of the bearing shaft that allows the passage of a second coolant. The first coolant is encapsulated in a gas-tight manner by a constructive connection formed between the focal track and the bearing part at least of the anode plate and the liquid-metal sliding bearing forms a thermal-conduction element for transferring thermal energy between the first coolant and the second coolant.
