Abstract: A multi-region target that is configured to selectively generate two different energy distributions when exposed to an excitation electron beam is described. The multi-region target includes multiple regions with different x-ray generating characteristics. Thus, the interaction between an excitation electron beam and the target generates an x-ray beam with an energy distribution that depends upon which target region is exposed to the excitation electron beam. The different x-ray spectra may be used to produce an enhanced contrast x-ray image. A method of detecting the rotational position of the multi-region target based upon the contrast level of the resulting images also is described.

Abstract: Provided are a high-quality and high-reliability rotary anode target for X-ray tubes, of which the mechanical strength at high temperatures is increased and which is applicable not only to low-speed rotation (at least 3,000 rpm) but also even to high-speed rotation at high temperatures, and also a method for producing it. The rotary anode has a two-layered structure to be formed by laminating an Mo alloy substrate that comprises from 0.2% by weight to 1.5% by weight of TiC with the balance of substantially Mo, and an X-ray generating layer of a W—Re alloy that overlies the substrate.

Abstract: An anode assembly for generating x-rays has a mounting block with a channel therethrough, with a diamond wafer mounted sealingly across an opening in the block so as to have an inner surface in contact with the coolant flowing in the channel. Alternatively, a thicker diamond member is mounted in the block with thermal conduction through the metal block. A metal anode film bonded to the outer surface of the diamond is receptive of a focused electron beam to generate x-rays. The diamond provides cooling in compensation for the film being heated by the electron beam. The assembly is useful in a scanning x-ray monochromator instrument for chemical analysis of a specimen surface.

Abstract: An x-ray tube source is disclosed that allows differential phase shift, attenuation, and x-ray scattering features of an object to be acquired in a single exposure. Such multiplexed x-ray tube source includes multiple x-ray spot origins controlled in such a way that each slightly separated spot is temporally modulated “ON and OFF” at differing frequencies. In an x-ray interferometer system, such x-ray tube source forms multiple illumination beams of a single angular view of an object's feature but each with different interference fringe locations. A composite image can be acquired with a high frame-rate digital detector as a component element in such x-ray interferometer system. Such composite image can be subsequently de-multipexed and separately presented according to each spot-source illumination beam. Such isolated images of an object's feature, each having different fringe locations, allows for post-acquisition “fringe-mapping” analysis of the feature's full interaction with x-rays, including refraction, scattering, and absorption.

Abstract: An anode for an X-ray tube can include one or more of an yttrium-oxide derivative, titanium diboride, boron carbide, titanium suboxide, reaction-bonded silicon carbide, and reaction-bonded silicon nitride. Upon collision with an anode, the kinetic energy of an electron beam in an X-ray tube is converted to high-frequency electromagnetic waves, i.e., X-rays. An anode from one or more of the above materials and a gradient distribution of conductive metals can reduce costs and/or weight, extend the life of the anode or associated components (e.g., bearings) and simultaneously provide a higher heat storage capacity as compared to traditional molybdenum and tungsten anodes.
