The Main Structure Of X-ray Tube

Aug 28, 2017

The main structure of X-ray tube (1) cathode (electron gun) is to generate electrons and focus the electron beam, tungsten wire firing spiral, through the current tungsten wire heat release free electrons. (2) Anode (metal target): Emitting X-rays, anode targets are usually made of metal materials with high heat transfer and good melting point, such as copper, drilling, nickel, iron, aluminum and so on. (3) The window is an X-ray-emitting channel, usually with 2 or 4 windows; The window material requires both a strength of the structure to maintain a high vacuum in the tube and a smaller absorption of x-rays.
