Abstract: According to one aspect of the invention a robust anode structure and methods of making and using said structure to produce ionizing radiation are disclosed. An ionizing radiation producing layer is bonded to the target side of a highly conductive diamond substrate, by a metal carbide layer. The metal carbide layers improves the strength and durability of the bond, thus improving heat removal from the anode surface and reducing the risk of delaminating the ionizing radiation producing layer, thus reducing degradation and extending the anode's life. A smoothing dopant is alloyed into the radiation producing layer to facilitate keeping the layer surface smooth, thus improving the quality of the x-ray beam emitted from the anode. In an embodiment, the heat sink comprises a metal carbide skeleton cemented diamond material. In another embodiment, the heat sink is bonded to the diamond substrate structure in a high temperature reactive brazing process.

Abstract: A compact x-ray source includes an electron beam source with a metallic film on a diamond window. The metallic film, which may be copper or scandium, absorbs the electron beams and produces k-alpha x-rays. The diamond window is a single crystal of diamond with a crystallographic orientation to diffract the x-rays, thereby producing a monochromatic and well collimated x-ray beam. The orientation of the crystal lattice may be configured to produce multiple x-ray beams. A plurality of electron beam sources may also be used to generate multiple x-ray beams. A detector is used to receive the x-ray beam after it interacts with a sample to be measured.

Abstract: The invention relates to a method for manufacturing a highly heat-conductive heat sink from carbon material, in particular, a rotatable anode heat sink of an X-ray tube, comprising an anode body rotatable on a rotational axis with a focal ring that runs perpendicularly to the axis and is heat conductively connected to the heat sink.

Abstract: A radiation source which can emit X-ray flux, UV-C flux and other forms of radiation uses electron beam current from a cathode array formed on the window through which the radiation will exit the source. The source can be made in formats which are compact or flat compared with prior art radiation sources. X-ray, UV-C and other radiative flux produced by the source can be used for such purposes as radiation imaging, sterilization, decontamination of biohazards, UV curing or photolithography.

Abstract: An x-ray source provides both a line focus output and a point focus output, and is mounted on a rotatable support to allow easy changing between the two. A housing has ports at different angular positions relative to an anode, and each port has an associated optic appropriate for an x-ray beam passing through that port. Three or four ports may also be used to allow for different types of beam conditioning. The different beam optics may also do conditioning based on wavelength, and the anode may be of a composite material to provide different wavelength ranges. The rotatable support may be manual or motorized, and a lockout mechanism may be used to ensure that only one port is active at a time. The support may also be located on a movable table that is movable in multiple perpendicular directions.

Abstract: An x-ray tube and method of operating include a vacuum chamber vessel and a source of an electron beam inside the vacuum chamber vessel. A target disposed inside the vacuum chamber vessel includes a substrate and one or more deposits attached to the substrate. Each different deposit includes an atomic element having a different atomic number. The x-ray tube also includes a means for directing the electron beam to a selectable deposit of multiple deposits. The substrate material can be selected with better vacuum sustaining strength, x-ray transparency, melting point, and thermal conductivity than a deposit. The substrate may be cooled by an integrated cooling system. The x-ray tube allows a selectable x-ray frequency to be produced with enhanced economy of power, reduced moving parts, and reduced size. For improved bone mass applications, one of the deposits has a k-fluorescence energy less than about 53 thousand electron volts.
