Abstract
In a device for generating X-rays or electron beams the cathode of the device is mounted on a ceramic insulator which becomes hot during operation, and the ceramic insulator is cooled by a fluid coolant flowing around the outside of the insulator at the remote end of the insulator, away from the cathode. The coolant conduit can be formed by flange rings, soldered directly on to the surface of the insulator, and the conduit may be shaped such that the coolant is in direct contact with the insulator. A method for manufacturing the de ice is also described.
Claims19
Device for generating X-rays or an electron beam, the device comprising:
- a vacuum enclosure for enclosing one or more electron emitter components in a vacuum,
- an insulation element in thermal contact, at a first region of the insulation element, with one or more of the electron emitter components in the vacuum enclosure,
- cooling means for cooling insulation element
- wherein
- the cooling means comprises a coolant conduit for conveying coolant fluid such that the coolant fluid flows in contact with a second region of the insulation element.
Method of manufacturing a device for generating X-rays or electron beams, the device comprising a substantially longitudinal insulation element and a vacuum enclosure for enclosing an electron emitter assembly in a vacuum, the electron emitter assembly being mounted at a first region of the insulating element, inside the vacuum enclosure.
- the method comprising a conduit-forming step, in which a coolant conduit is formed at a second region of the insulating element, outside the vacuum enclosure and/or in a wall of the vacuum enclosure, such that coolant fluid flowing in the coolant conduit can flow in contact with the second region of the insulation element.
