| titleOfInvention | Focusing type cold cathode X-ray tube |
| abstract | The invention discloses a focusing type cold cathode X-ray tube which comprises a field emission cold cathode, a lamp filament gate electrode formed by lamp filaments, an anode, an X-ray tube case and a ray emergence window, wherein the field emission cold cathode and the anode are respectively arranged at two ends inside the X-ray tube case and are respectively extracted to the outside of the X-ray tube case through a cathode extraction electrode and an anode extraction electrode; the lamp filament gate electrode is arranged between the field emission cold cathode and the anode; two side surfaces of the lamp filament gate electrode are extracted to the outside of the X-ray tube case through the two extraction electrodes; the anode is provided with a slope surface for generating an X-ray by electron bombardment; and the ray emergence window is arranged at the position on the side surface of the e X-ray tube case, which is just opposite to the slope surface. Compared with the general field emission cold cathode X-ray tube, the focusing type cold cathode X-ray tube can be used for effectively carrying out electron bombardment on the anode to degass, improving the vacuum degree in the X-ray tube, simultaneously focusing electron beams, improving the performance of the X-ray tube and prolonging the service life of the X-ray tube. |
