摘要: A getter support capable of permitting a getter to be compactly arranged in a vacuum envelope while keeping a space for the getter minimized. The getter support includes holders for vertically interposedly holding a getter, first support legs formed integrally with the holders so as to downwardly extend therefrom, and second support legs formed integrally with the holders so as to upwardly extend therefrom. The getter support is fixedly arranged in a getter chamber while being pressed by elasticity of the second support legs. The second support legs are varied in deflection depending on contact thereof with a second substrate of an envelope. This permits a distance between an upper surface of the getter and the second substrate of the envelope to be constantly kept at a desired value.

摘要: Provided is an X-ray tube which can perform stable X-ray radiation under a desired condition in a radiation region extending in a predetermined direction. Included are a base plate having an opening portion and made of alloy 426, an X-ray transmission window made of titanium foil and arranged to close the opening portion of the base plate, a flat box-like vessel portion attached to the base plate and inside of which is in a vacuum state, an X-ray target provided at the opening portion in the vessel portion, and an electron source injecting electrons to the X-ray target in the vessel portion. The electron source includes a liner cathode, a first control electrode pulling out electrons from the cathode and a second control electrode restricting radiation range of the pulled-out electrons. At this time, X-rays emitted from the X-ray window spreads radially from opening shape of the opening portion.
