X-ray target.High-Power transmission target has an interaction layer of tungsten tungsten (tŭng`stən) [Swed.,=heavy stone], metallic chemical element; symbol W; at. no. 74; at. wt. 183.85; m.p. about 3,410°C;; b.p. 5,660°C;; sp. gr. 19.3 at 20°C;; valence +2, +3, +4, +5, or +6. and a special backing layer that provides improved heat transfer and lower focal spot focal spot, n See spot, focal. focal spot the area on the target of the x-ray tube which the electron stream strikes and from which x-rays are emitted. Called also focus. temperature. Users can operate the x-ray tube X-ray tube An electronic device used for the generation of x-rays. X-rays are produced in the x-ray tube by accelerating electrons to a high velocity by an electrostatic field and then suddenly stopping them by collision with a solid body, the so-called with higher energies at the highest possible resolution, for increased image contrast. Ideal for inspecting low contrast structures or high absorption structures. Feinfocus, feinfocus.com |
