    Abstract: A compact source for high brightness x-ray generation is disclosed. The higher brightness is achieved through electron beam bombardment of multiple regions aligned with each other to achieve a linear accumulation of x-rays. This may be achieved by aligning discrete x-ray sub-sources, or through the use of x-ray targets that comprise microstructures of x-ray generating materials fabricated in close thermal contact with a substrate with high thermal conductivity. This allows heat to be more efficiently drawn out of the x-ray generating material, and in turn allows bombardment of the x-ray generating material with higher electron density and/or higher energy electrons, leading to greater x-ray brightness.Some embodiments of the invention comprise x-ray optical elements placed between sub-sources of x-rays. These x-ray optical elements may form images of one or more x-ray sub-sources in alignment with other x-ray sub-sources, and may enhance the linear accumulation that can be achieved.

    Abstract translation: 公开了用于高亮度x射线产生的紧凑源。 通过彼此对准的多个区域的电子束轰击实现较高的亮度，以实现x射线的线性积累。 这可以通过对齐离散x射线子源或通过使用包含与具有高导热性的基底紧密热接触制造的x射线产生材料的微结构的x射线靶来实现。 这样可以更有效地将热量从X射线产生材料中拉出，并且进而允许以更高的电子密度和/或更高能量的电子轰击x射线产生材料，导致更大的x射线亮度。 本发明的一些实施例包括放置在x射线的子源之间的x射线光学元件。 这些X射线光学元件可以形成与其他x射线子源对准的一个或多个x射线子源的图像，并且可以增强可以实现的线性累积。

    Abstract: Provided is an anode for an X-ray generating tube, which reduces a drop in the quality of an emitted X-ray due to the history of X-ray emitting operation. A target layer is formed on the inside of the edge of a support substrate. An end portion of an extended portion of a joining member, which protrudes over a support surface of the support substrate, is covered with a conductive member higher in melting point than the joining member. The conductive member is electrically connected to the target layer, thereby electrically connecting the joining member to the target layer.
