Abstract: An x-ray source for computer tomography uses several sub-sources. An electron beam impacts the several sub-sources to achieve a high x-ray flux with high resolution. The several sub-sources produce a composite image, which is deconvolved to disentangle the composite image and render a useful image. The configuration of the several sub-sources can be optimized for a given specimen structure.

Abstract: A composite target is provided and is interacted with an electron to generate an X-ray, and an energy of the electron can be changed by controlling a tube voltage at least. The composite target includes a target body and an interposing layer which is connected with the target body. The interposing layer moves a highest peak of an energy spectrum of the X-ray toward a high energy direction. The interposing layer may be a single metal or a metal mixture. Not only a low energy photon of the X-ray can be filtered by the interposing layer, but also a distribution of the low energy photon of the X-ray can be increased by increasing a thickness of the interposing layer. As the tube voltage is enhanced, an amount of a high energy photon of the X-ray generated is dramatically increased. An X-ray tube containing the above composite target is also provided.

Abstract: Methods for generating a multiple-energy X-ray pulse. A beam of electrons is generated with an electron gun and modulated prior to injection into an accelerating structure to achieve at least a first and specified beam current amplitude over the course of respective beam current temporal profiles. A radio frequency field is applied to the accelerating structure with a specified RF field amplitude and a specified RF temporal profile. The first and second specified beam current amplitudes are injected serially, each after a specified delay, in such a manner as to achieve at least two distinct endpoint energies of electrons accelerated within the accelerating structure during a course of a single RF-pulse. The beam of electrons is accelerated by the radio frequency field within the accelerating structure to produce accelerated electrons which impinge upon a target for generating Bremsstrahlung X-rays.

Abstract: An x-ray device utilizes a band of material to exchange charge through tribocharging within a chamber maintained at low fluid pressure. The charge is utilized to generate x-rays within the housing, which may pass through a window of the housing. Various contact rods may be used as part of the tribocharging process.
