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: 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.
