Staionary anode type X-ray Tube to have non-evaporable getter

摘要

The present invention relates to a fixed anode X-ray tube equipped with a non-diffusion getter for improving the vacuum durability, which is a core technical element of the X-ray tube, and more particularly, a non-diffusion getter mounted on the cathode for adsorption of residual gas after the X-ray tube is sealed. It relates to a fixed anode X-ray tube, An exterior bulb, a cathode fixedly mounted inside the exterior bulb and having a filament installed therein, one side mounted inside the exterior bulb and the other side protruding to the outside, an inclined target in which the electron beam generated from the filament collides is mounted In the fixed anode X-ray tube equipped with a non-diffusion getter composed of an anode, the cathode comprises: a cathode collecting tube having a filament mounted thereon; a collecting tube supporting tube that covers and supports the outside of the cathode collecting tube; A fixed anode X-ray tube equipped with a non-diffusion getter, characterized in that it is mounted on the front of the cathode collecting tube and formed of a filament emitting electrons, and the non-diffusion getter is formed in a structure in which the anode and the anode are oriented and exposed on the front side of the cathode collecting tube. provides
