X-ray tube |
摘要 |
An x-ray tube 100 mainly includes an electron gun assembly 110 and a target assembly 210 which are arranged at right angles. In the target assembly 210, an x-ray target 211 is enclosed in a cylindrically-shaped hood electrode 212. Electrons emitted from the electron gun assembly 110 enters the hood electrode through an electron beam opening 215 to collide with the x-ray target 212, whereupon x-rays are generated. X-rays travel in an x-ray emitting direction R along the central axis of the hood electrode to emit outside of the hood electrode through an x-ray opening 216. A protrusion 212a is formed on the periphery of the hood electrode 212 downstream of the electron opening 215 in the x-ray emitting direction R.
