X-ray apparatus |
摘要 |
This invention aims at providing an X-ray apparatus having a stable X-ray output. Since the focus electrode of the X-ray tube of the X-ray apparatus according to this invention maintains a ground potential, the focus diameter of electrons bombarded against a target becomes constant. Hence, the X-ray output emerging from an exit window is stabilized. Since the potential ratio of a cathode to the target is always constant, the electric field distribution between the cathode and the target is stabilized, thereby stabilizing the X-ray output emerging from the exit window.
