摘要： An X-ray tube device according to the present invention includes a cathode generating an electron beam, an anode generating an X-ray by collision of the electron beam from the cathode, an envelope internally housing the cathode and the anode, a magnetic field generator including a magnetic pole arranged to be opposed to the envelope, generating a magnetic field for focusing and deflecting the electron beam from the cathode to the anode, and an electric field relaxing electrode arranged between the magnetic pole and the envelope, having an outer surface having a rounded shape. Thus, the magnetic field generator can be placed closer to the envelope while a tip end of the magnetic field generator is suppressed from being a discharge start point, and hence the effect of being capable of downsizing the X-ray tube device is achieved.

摘要： A metal including a passivation film 33a with a thickness of 10 nm or more is used as a metal electrode (a focus cup electrode 33) for generating an electric filed in a vacuum. The focus cup electrode 33 is made of stainless steel. The stainless steel is immersed in a treatment solution to perform coating (passivation treatment) . Accordingly, the passivation film 33a can be formed to be thicker than 10 nm. In this manner, the passivation film 33a is thicker than 10 nm. Therefore, the surface is uniform, and the adhesion is excellent, and the number of pinholes is small. Accordingly, the withstand voltage performance can be improved.
摘要翻译：使用包括厚度为10nm以上的钝化膜33a的金属作为用于在真空中产生电场的金属电极（聚焦杯电极33）。聚焦杯电极33由不锈钢制成。将不锈钢浸入处理溶液中以进行涂覆（钝化处理）。因此，钝化膜33a可以形成为比10nm厚。以这种方式，钝化膜33a比10nm厚。因此，表面均匀，粘附性优异，针孔数少。因此，能够提高耐压性能。
