X-RAY TUBE AND METHOD OF MANUFACTURING THE SAME |
摘要 |
According to one embodiment, an X-ray tube includes an envelope with an opening, an X-ray transmission assembly mounted on the envelope and vacuum-tightly blocking the opening, a cathode and an anode target. The X-ray transmission assembly includes a window frame, an X-ray transmission window, an X-ray-resistive resin film, a sealing member and a dry gas. The X-ray transmission window is formed of a beryllium thin plate, accommodated in the window frame, and configured to maintain, along with the window frame, a vacuum-tight state inside the envelope. The X-ray-resistive resin film forms a space inside along with the window frame and the X-ray transmission window. The dry gas fills the space. |

1. An X-ray tube comprising:
an envelope comprising an opening; an X-ray transmission assembly mounted on the envelope and vacuum-tightly blocking the opening; a cathode accommodated in the envelope and configured to emit electrons; and an anode target accommodated in the envelope and configured to emit X-rays, wherein the X-ray transmission assembly comprises, a window frame opposing the opening and vacuum-tightly mounted to the envelope, an X-ray transmission window formed of a beryllium thin plate, accommodated in the window frame, and configured to maintain, along with the window frame, a vacuum-tight state inside the envelope and transmit X-rays, an X-ray-resistive resin film located in the atmosphere side from the window frame, opposing the X-ray transmission window with a gap between the X-ray-resistive resin film and window frame, and configured to form a space inside along with the window frame and the X-ray transmission window, a sealing member configured to air-tightly block the gap between the window frame and the X-ray-resistive resin film to maintain an airtight state of the space, and a dry gas filled in the space. |
