| 发明名称 | X-ray tube | ||
| 摘要 | An X-ray tube includes a vacuum tube. A field emission cathode structure and an anode spaced from each other are located in the vacuum tube. The field emission cathode structure includes a first metal plate, a second metal plate, and an electron emitter. The electron emitter is fixed between the first metal plate and the second metal plate. One end of the electron emitter extends out of the first metal plate and the second metal plate to act as an electron emission end. | ||
