摘要： An X-ray tube 1 includes spacer 8 which is cylindrical so it does not block electrons 80 directed from a grid electrode 72 toward a focusing electrode 25, and which has one end 8b fixed to the grid electrode 72 and the other end 8c abutting against the focusing electrode 25. The distance between the grid electrode 72 and focusing electrode 25 is set to a predetermined distance by the spacer 8.

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.

摘要翻译： 本发明的目的在于提供一种具有稳定的X射线输出的X射线装置。 由于根据本发明的X射线装置的X射线管的聚焦电极保持接地电位，所以与目标轰击的电子的聚焦直径变得恒定。 因此，从出口窗口出来的X射线输出稳定。 由于阴极与目标的电位比率总是恒定的，所以阴极和目标之间的电场分布是稳定的，从而稳定了从出射窗口出来的X射线输出。
