    Abstract: An X-ray emitting target including a diamond substrate, a first layer disposed on the diamond substrate and including a first metal, and a second layer disposed on the first layer and including a second metal whose atomic number is 42 or more and which has a thermal conductivity higher than that of the first metal. Carbide of the first metal is present at a boundary between the diamond substrate and the first layer. The target is prevented from overheating, so that output variation due to rising temperature is suppressed. Thus it is possible to emit stable and high output X-rays.

    Abstract: The present invention refers to hybrid anode disk structures for use in X-ray tubes of the rotary anode type and is concerned more particularly with a novel light weight anode disk structure (RA) which comprises an adhesion promoting protective silicon carbide (SiC) interlayer (SCI) deposited onto a rotary X-ray tube's anode target (AT), wherein the latter may e.g. be made of a carbon-carbon composite substrate (SUB′). Moreover, a manufacturing method for robustly attaching a coating layer (CL) consisting of a high-Z material (e.g. a layer made of a tungsten-rhenium alloy) on the surface of said anode target is provided, whereupon according to said method it may be foreseen to apply a refractory metal overcoating layer (RML), such as given e.g. by a tantalum (Ta), hafnium (Hf), vanadium (V) or rhenium (Re) layer, to the silicon carbide interlayer (SCI) prior to the deposition of the tungsten-rhenium alloy. The invention thus leverages the tendency for cracking of the silicon carbide coated carbon composite substrate (SUB′) during thermal cycling and enhances adhesion of the silicon carbide/refractory metal interlayers to the carbon-carbon composite substrate (SUB′) and focal track coating layer (CL) by an interlocking mechanism. Key aspects of the proposed invention are: a) controlled formation of coating cracks (SC) in the silicon carbide layer (SCI) and b) conformal filling of SiC crack openings with a refractory metal.

    Abstract: A radiation-transmissive type target structure includes a target layer formed on a substrate. The target layer has a thickness equal to or less than 20 μm, and is configured to generate radiation in response to irradiation of electrons. A surface of the target layer is formed with projecting portions and depressed portions, the depressed portions have a depth of at least half the thickness of the target layer. Advantageously, separation of the target layer at an interface between the substrate and the target layer is substantially prevented. A radiation generating apparatus and a radiography system equipped with the target structure are also disclosed.
