    Abstract: An X-ray imaging system utilizing a pixelated X-ray source and a X-ray imaging detector operated synchronously. The imaging system may be used in industrial and medical applications. The X-ray source and X-ray detector are synchronized such that a corresponding area of the X-ray detector is activated when the corresponding area of the X-ray source is emitting X-rays. Synchronized and adaptive emission and detection of the X-rays results in scatter rejection, improved image quality, and optimum exposure and dose reduction.

    Abstract: An x-ray tube assembly (16) includes a vacuum envelope (52) and an x-ray permeable exit window (58). An anode (50) is positioned within the vacuum envelope (52) such that a near side is adjacent to the exit window (58) and a far side is opposite thereof. A cathode assembly (66) is also mounted within the vacuum envelope (52) which directs an electron beam (72) toward a focal spot or point (62) on the far side of the anode (50). The anode further includes a central cavity or indentation (70) which provides a location for mounting a set of radiation attenuating vanes (64) in addition to a shaped x-ray filter or compensator (68). Close placement of the vanes (64) and the filter (68) relative to the focal spot of the anode desirably reduce off focal radiation and allow beam shaping. An externally located collimator (18) further shapes the output x-ray beam.

    Abstract: A method and a device for generating extreme ultraviolet (EUV) and soft x-ray radiation from a gas discharge. The device has at least two electrodes each having a flush opening by which an axis of symmetry is defined, in which an intermediate space with a wide spatial homogenous gas filling between anode and cathode is provided. The electrodes are formed in such a way, that the gas discharge is formed exclusively in the volume defined by the flush openings. The current pulses with respect to amplitude and period duration are selected in such a way that a dense hot plasma channel is formed on the axis of symmetry, the plasma being the source of EUV and/or soft x-ray radiation. The preferred area of application is the EUV projection lithography in the spectral range around 13 nm.

    Abstract: An X-ray generator includes a hermetically sealed main generator unit, and an electron gun and a target housed inside the main generator unit, and bombards the target with electrons emitted from the electron gun and passes an X-ray beam emitted from the surface of the target owing to the bombardment to the exterior through an exit window. An X-ray optical element is provided inside the main generator unit on the output path of the X-ray beam emitted from the target for regulating the X-ray beam and the X-ray beam regulated by the X-ray optical element is passed through the exit window. This configuration improves the durability of the X-ray optical element and enables the length of the X-ray path to the X-ray irradiation point to be shortened so as to suppress attenuation of the emitted X-ray beam by air resistance and thereby reduce power consumption.

    Abstract: A technology for generating femtosecond time regime x-ray pulses for application to the study of the structure and reactions of biological molecules, photosynthesis reactions, semiconductor device fabrication, structural determination and dynamic performance, and other chemical, biological and physical processes taking place on sub-picosecond time scales. Electrons are accelerated to hundreds of keV to tens of MeV energies using high energy, femtoseconds duration laser pulses, and are then converted to x-rays by one of several physical processes. Because the laser accelerated electrons have the pulse width of the laser driver, extremely short (less than 100 femtoseconds) x-ray pulses can be produced from these electrons. The x-ray energy and emittance can be controlled by electron beam production and beam transport techniques and/or collimators or x-ray optical systems. The use of laser acceleration and novel electron to x-ray conversion processes should result in significantly lower costs than current synchrotron-based x-ray sources, and lead to widespread introduction of this tool into commercial biological and medical x-ray and materials structure research laboratory environments. In addition, multi-beam sources of electrons from conventional electron devices, such as field emission diodes and thermionic emission devices, can be used in conjuction with novel x-ray beam combining techniques to produce a long pulse, high flux collimated x-ray beam suitable for use in biological x-ray crystallography studies.
