摘要： The present invention relates to an X-ray tube, having a structure enabling capturing of a clear magnified transmission image and enabling increase of a magnification factor of the magnified transmission image, and an X-ray source including the X-ray tube. In the X-ray tube, X-rays are generated by making electrons from an electron gun incident onto an X-ray target of an anode, disposed inside an anode housing unit, and the generated X-rays are taken out from an X-ray emission window. In particular, the anode housing unit has a pair of conductive flat portions disposed parallel to a reference plane, orthogonal to an electron incidence surface of the X-ray target, and so as to sandwich the X-ray target. The reference plane contains a first reference line, joining an electron emission exit center of the electron gun and an electron incidence surface center of the X-ray target, and a second reference line, being a straight line intersecting the first reference line on the electron incidence surface of the X-ray target and joining the electron incidence surface center and an X-ray emission window center.

摘要： The present invention relates to an X-ray tube in which X-rays are generated by making electrons from an electron gun incident onto an X-ray target of an anode, disposed inside an anode housing unit, and the generated X-rays are taken out from an X-ray emission window. The anode has a straight main body and a protruding portion, extending along an axis line direction of the main body from a tip of the main body. An inclined surface, onto which the electrons emitted from the electron gun collide, and a pair of side surfaces, disposed in parallel while sandwiching the inclined surface, are formed on the protruding portion. A distance between the pair of side surfaces of the protruding portion is shorter than a width of the main body in the same direction as the distance.

摘要： An x-ray emitting window is formed at a front end face, and a taper surface tilted with respect to the x-ray emitting direction is formed near the emitting window, whereby an object to be inspected can be prevented from abutting against the front end face even if the object is pivoted about an axis intersecting the emitting direction while the object is disposed closer to the x-ray emitting window. As a consequence, while the object is disposed closer to the x-ray emitting position, the orientation of the object can be changed. Therefore, when inspecting the internal structure of the object and the like by irradiating the object with x-rays and detecting the x-rays transmitted through the object, not only a magnified penetration image of the object with a high magnification rate is obtained, but also the internal structure of the object and the like can be verified in detail by changing the orientation of the object.
摘要翻译： X射线发射窗形成在前端面，并且在发射窗附近形成相对于x射线发射方向倾斜的锥形表面，由此可以防止被检查物体抵靠前端即使物体绕着与发射方向相交的轴线枢转，同时物体靠近X射线发射窗口设置。结果，当物体设置得更靠近x射线发射位置时，可以改变物体的取向。因此，当通过用X射线照射物体并检测透过物体的x射线来检查物体等的内部结构时，不仅获得了具有高放大率的物体的放大穿透图像，而且也可以通过改变物体的取向来详细地验证物体等的内部结构。
