Abstract: A light emitting sealed body includes: a housing which stores a discharge gas and is provided with a first opening to which first light is incident along a first optical axis and a second opening from which second light is emitted along a second optical axis; a first window portion which hermetically seals the first opening; a second window portion which hermetically seals the second opening; and a first electrode and a second electrode. The housing is formed of a light shielding material which does not transmit the first light and the second light. An internal space is defined by the housing, the first window portion, and the second window portion and the internal space is filled with the discharge gas. The first opening and the second opening are disposed so that the first optical axis and the second optical axis intersect each other.

Abstract: A light emitting sealed body includes: a housing containing light-emitting gas in an internal space and formed with an opening on which first light is incident and/or from which second light is emitted, wherein the first light is laser light for maintaining a plasma generated in the light-emitting gas and the second light is light from the plasma; and a window member that transmits the first light and/or the second light at the opening. The window member is joined to the housing by a joining material consisting of a material containing gold.

Abstract: A light emitting unit includes a light emitting sealed body and a voltage application circuit. The light emitting sealed body includes a container to which laser light for maintaining plasma is incident and from which light from the plasma is emitted, a first electrode which includes a first discharge portion, and a second electrode which includes a second discharge portion. An end portion of the first discharge portion has a shape in which a thickness is thinned as it goes toward the second discharge portion and an end surface of the second discharge portion extends along a plane perpendicular to an extending direction of the first discharge portion. The voltage application circuit controls a potential difference between the first electrode and the second electrode by adjusting a voltage applied to at least the first electrode.

Abstract: In an X-ray radiation source, a lid part is fastened to a main part with screws, so that an X-ray tube is secured to a housing while being pressed against an inner surface of the wall part a by a first circuit board. The X-ray tube can be secured stably within the housing by thus being held between the first circuit board and the wall part. The X-ray radiation source uses the first circuit board incorporated in the housing itself for pressing the X-ray tube. This makes it unnecessary to provide new members for pressing the X-ray tube and can prevent the device structure from becoming complicated.

Abstract translation: 在X射线辐射源中，用螺钉将盖部分固定在主体部分上，使得X射线管通过第一电路板按压到壁部a的内表面而固定在壳体上。 因此，通过将X射线管保持在第一电路基板与壁部之间，能够稳定地固定在壳体内。 X射线辐射源使用结合在壳体本身中的第一电路板来挤压X射线管。 这不需要提供用于按压X射线管的新构件，并且可以防止装置结构变得复杂。
