Abstract: Stationary x-ray target assemblies manufactured using a metal deposition process to form one or more metal layers of the target. In particular, the metal deposition process is used to form an x-ray target metal layer and/or a stress buffer zone on an x-ray target substrate. The stress buffer zone improves material properties of the metals and/or the bonding between the x-ray target metal layer and the substrate. Improved bonding between the x-ray target metal layer and the substrate also improves the heat dissipation properties of the stationary x-ray target assembly.

Abstract: An apparatus and method for the X-ray irradiation of materials is provided. This apparatus includes an irradiation chamber, a number of flat electromagnetic (X-ray) sources having a number of addressable cathode emitters, a support mechanism, a heat transfer system, a shielding system, and a process controller. A shielded portal within the shielding system allows access to an interior volume of the irradiation chamber. The electromagnetic sources are positioned on or embedded within interior surfaces of the irradiation chamber. These electromagnetic sources generate an electromagnetic flux, such as an X-ray flux, where this flux is used to irradiate the interior volume of the irradiation chamber and any materials placed therein. The operation of the electromagnetic sources and the number of addressable cathode emitters being controlled by the process controller. The materials placed within the interior of the chamber may be supported by a low attenuation support mechanism. This low attenuation support mechanism does not substantially reduce the X-ray flux intended to irradiate the materials placed within the interior volume of the irradiation chamber.

Abstract: The present invention provides an electrode, typically an anode, for use in an x-ray generating apparatus comprising an electron source. The electrode comprises a housing, a diamond member mounted to the housing, and a target located on the diamond member, which target in use is bombarded with electrons from the electron source so as to generate x-rays. A bonding layer is located between the housing the diamond member, which bonding layer comprises an alloy having a solidus or melting point of less than 900° C. A particularly preferred alloy comprises silver, copper and indium. This arrangement assists in dissipating heat generated at the electrode surface whilst retaining the structural integrity of the electrode.

Abstract: The present invention relates to an X-ray source for emitting a characteristic X-ray and a fluorescent X-ray analyzing apparatus using the X-ray source. A secondary target is arranged in superposition on a primary target. An electron beam generated by an electron gun enters the primary target, which passes and emits a continuous X-ray. The secondary target transmits and emits a characteristic X-ray excited by the continuous X-ray emitted from the primary target. The primary target and the secondary target are superposed one on the other, so that the continuous X-ray emitted from the primary target efficiently excites the secondary target thereby to efficiently generate the characteristic X-ray.

Abstract: A method for fabricating and the resulting x-ray target comprising metal deposited on an electrically-conductive base member by electrodeposition from a molten salt electrolyte is claimed. The method comprises submerging the base member in a molten salt electrolyte bath. The base member acts as a cathode and anodes of target material metals are activated by electrical circuitry to deposit a target layer onto the base member. The electrodeposition method results in an exceptionally dense and pure layer of tungsten or tungsten alloy. Target materials of tungsten, tungsten alloy, rhenium, and rhenium alloy produce good results when electrodeposited onto base members fabricated from molybdenum, molybdenum alloy, and graphite-or carbon-based composites.
