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.
摘要翻译： X射线管100主要包括以直角布置的电子枪组件110和靶组件210。在目标组件210中，x射线靶211被封闭在圆柱形罩电极212中。从电子枪组件110发射的电子通过电子束开口215进入发动机罩电极以与X射线靶212碰撞从而产生x射线。 X射线沿着发动机罩电极的中心轴线在x射线发射方向R上行进，通过X射线开口216发射到罩电极外部。突起212a形成在罩电极212的周围， x射线发射方向R上的电子开口215。
