Abstract: A multi-energy imaging system and method for selectively generating high-energy X-rays and low-energy X-ray beams are described. A pair of optic devices are used, one optic device being formed to emit high X-ray energies and the other optic device being formed to emit low X-ray energies. A selective filtering mechanism is used to filter the high X-ray energies from the low X-ray energies. The optic devices have at least a first solid phase layer having a first index of refraction with a first photon transmission property and a second solid phase layer having a second index of refraction with a second photon transmission property. The first and second layers are conformal to each other.

Abstract: A gas tight radiation window membrane comprises a layered diffusion barrier with a reactive metal layer (201) covered on both sides by cover layers (202, 203). An originally continuous carrier layer (101) can be made a mesh that has openings coincident with openings of a reinforcement grid (105), while the gas tight diffusion barrier (107, 507) spans as a continuous film over said openings in said mesh.

Abstract: An extended radiating aperture for X-rays is provided by means of a stationary target of a heavy metal positioned for uniform illumination by high speed electrons emanating from a cathode and accelerating through a difference of potential between the cathode and the target. The target is in the form of a relatively thin film which can be deposited on a substrate transparent to Xradiation. A layer of fluorescent material is placed adjacent the substrate on the opposite side thereof from the target so that Xrays generated within the target material pass through the target material and impinge on the fluorescent layer. The fluorescent material enhances the monochromaticity of the X-ray spectrum by emitting fluorescent X-radiation while substantially absorbing incident X-radiation having energies above the fluorescent radiation spectrum. A zone plate is positioned adjacent the fluorescent layer to spatially modulate the radiation of the radiating aperture to provide this radiation with a spatial frequency spectrum suitable for obtaining high resolution roentgenograms. The zone plate provides a coding on the roentgenogram which is then decoded by an optical processor to form a visible image of an object being X-rayed. Alternative embodiments of the invention include the use of an inclined transmissive target, a transmissive target having serrations, and the use of a moire pattern mask between the target and the fluorescent material to augment fluorescent radiation from the target and to inhibit the passage of X-radiation normal to the layer of fluorescent material.

Abstract: The invention provides a method of vacuum-tight closure of beryllium windows of X-ray tubes and especially thin windows for use in X-ray fluorescence analysis of elements of a low atomic number, said windows having a thickness of only about 50 Mu . The window material or the ready windows are for this purpose provided by a known method of sputtering material particles with an extremely thin layer of beryllium or beryllium oxide. The practically unavoidable pores or cracks in the beryllium foil are found to be completely closed by a layer thickness of about 1 Mu . By this method rejects in the production due to bad vacuumtightness can be avoided and it becomes thus possible to manufacture reliable X-ray tubes provided with these extremely thin windows.
