| 摘要 |
The present invention relates to an X-ray tube with non-evaporable getters disposed therein for maintaining a degree of vacuum sufficient to operate the X-ray tube. The present invention provides a fixed-anode X-ray tube and a rotating-anode X-ray tube in which non-evaporable getters are disposed. The X-ray tubes, even when rated power is introduced without an aging process, can perform gas adsorption sufficiently and stably during operation, despite gases that can be generated by the filament and the cathode focusing cap and gases that can be generated by the target. |
