    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: According to one embodiment, a photon counting CT apparatus includes an X-ray source, a photon counting CT detector, and a calibration unit. The X-ray source includes a cathode configured to generate electrons and an anode including a plurality of targets configured to generate a plurality of characteristic X-rays having different energies. The photon counting CT detector detects X-ray photons generated by the X-ray source. The calibration unit calibrates the gain of the photon counting CT detector based on the correspondence relationship between the photon energies of the plurality of characteristic X-rays and outputs from the photon counting CT detector.

    Abstract: This disclosure presents systems for x-ray illumination that have an x-ray brightness several orders of magnitude greater than existing x-ray technologies. These may therefore useful for applications such as trace element detection or for micro-focus fluorescence analysis.The higher brightness is achieved in part by using designs for x-ray targets that comprise a number of microstructures of one or more selected x-ray generating materials fabricated in close thermal contact with a substrate having high thermal conductivity. This allows for bombardment of the targets with higher electron density or higher energy electrons, which leads to greater x-ray flux.The high brightness/high flux x-ray source may then be coupled to an x-ray optical system, which can collect and focus the high flux x-rays to spots that can be as small as one micron, leading to high flux density.
