    摘要： A charged-particle beam lens includes a plate-like anode, a plate-like cathode, and an insulator disposed between the anode and the cathode. The insulator, the anode, and the cathode have a passage portion through which a charged beam is passed. A high-resistance film is formed on an inner side of the insulator, the inner side forming the passage portion, or an outermost side of insulator, and the anode and the cathode are electrically connected together via the high-resistance film. The anode and the high-resistance film, and the cathode and the high-resistance film each contain the same metal or semiconductor element and have different resistant values. This suppresses electric field concentration due to an increase in resistance and poor connection at the interface between the anode and the cathode and the high-resistance film or at the interface between the electroconductive film and the high-resistance film, thus suppressing generation of discharge.

    摘要翻译： 带电粒子束透镜包括板状阳极，板状阴极和布置在阳极和阴极之间的绝缘体。 绝缘体，阳极和阴极具有带电束通过的通道部分。 在绝缘体的内侧形成高电阻膜，形成绝缘体的通路部分或最外侧的内侧，并且阳极和阴极通过高电阻膜电连接在一起。 阳极和高电阻膜以及阴极和高电阻膜各自含有相同的金属或半导体元件，并具有不同的电阻值。 由于电阻增加和阳极与阴极与高电阻膜之间的界面或导电膜与高电阻膜之间的界面处的接合不良而抑制电场集中，因此抑制了放电的产生。

    摘要： A radiation generating apparatus includes a radiation generation tube including an electron emitting source having an electron emitting member, a transmission type target, a tubular backward shielding member having an electron passing hole facing the target layer at one end, located at the electron emitting source side of the transmission type target, and connected to the periphery of the base member. The radiation generating apparatus further includes a collimator having an opening for defining an angle for extracting the radiation at the opposite side of the electron emitting source side of the transmission type target, and an adjusting device connected to the collimator, and configured to vary an opening diameter of the opening, wherein the target layer has a portion separated from a connection portion of the base member and the backward shielding member at the periphery.
