X-ray tube having anode electrode

摘要

Provided is an X-ray tube. The X-ray tube includes an electrode on which an electron beam impacts to generate an X-ray, and a window on which the electrode is disposed and through which the X-ray generated from the electrode is transmitted. The electrode includes a channel passing through the electrode, and the electron beam is provided into the channel to generate the X-ray.

1. An X-ray tube comprising:
an electrode on which an electron beam is incident to generate an X-ray; and a window disposed on the electrode, the generated X-ray from the electrode being transmitted through the window, wherein the electrode comprises a channel passing through the electrode, wherein the channel includes a lower channel having a truncated shape with an inclined inner sidewall and an upper channel having a cylindrical shape with a vertical inner sidewall extending from a top surface of the lower channel, a width of the top surface of the lower channel being equal to a width of a bottom surface of the upper channel, and wherein the electron beam is incident on the inner sidewall of the lower channel to generate the X-ray, the electron beam travelling from a bottom surface of the lower channel to the top surface of the lower channel.
