ANODE AND X-RAY GENERATING TUBE, X-RAY GENERATING APPARATUS, AND RADIOGRAPHY SYSTEM THAT USE THE ANODE

摘要

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.

主权项

1. An anode, comprising:
a target layer configured to generate an X-ray; a support substrate, which extends farther outwardly than an edge of the target layer, the support substrate comprising a support surface where the target layer is supported; a tubular anode member, which is joined to a side surface of the support substrate via a joining member, the joining member comprising an extended portion, which extends from the side surface to the support surface, a conductive member that has a melting point higher than a melting point of the joining member, and wherein the joining member is electrically connected to the target layer by covering the extended portion with the conductive member.
