摘要： An x-ray source assembly and method of operation are provided having enhanced output stability. The assembly includes an anode having a source spot upon which electrons impinge and a control system for controlling position of the anode source spot relative to an output structure. The control system can maintain the anode source spot location relative to the output structure notwithstanding a change in one or more operating conditions of the x-ray source assembly. One aspect of the disclosed invention is most amenable to the analysis of sulfur in petroleum-based fuels.

摘要： A unitary support device for a polycapillary optic is provided wherein a housing has a central opening therethrough and at least two locating structures, such as positioning shoulders, formed therein. Each locating structure is sized and positioned to accommodate a different polycapillary positioning component within the housing. Each polycapillary positioning component has at least one opening for holding at least one polycapillary of the polycapillary optic. One or more coaxial bores can define the central opening of the housing and the locating shoulders in one continuous fabrication operation. Depending upon the polycapillary positioning components employed, i.e., location of the openings therein for accommodating the polycapillaries, the positioning components can be oriented within the housing such that radiation from one of a divergent beam, a focused beam, or a parallel beam is collected by the optic, and such that the optic can output one of a collimated beam, a focused beam or a divergent beam.

摘要： An x-ray analysis apparatus for illuminating a sample spot with an x-ray beam. An x-ray tube is provided having a source spot from which a diverging x-ray beam is produced having a characteristic first energy, and bremsstrahlung energy; a first x-ray optic receives the diverging x-ray beam and directs the beam toward the sample spot, while monochromating the beam; and a second x-ray optic receives the diverging x-ray beam and directs the beam toward the sample spot, while monochromating the beam to a second energy. The first x-ray optic may monochromate characteristic energy from the source spot, and the second x-ray optic may monochromate bremsstrahlung energy from the source spot. The x-ray optics may be curved diffracting optics, for receiving the diverging x-ray beam from the x-ray tube and focusing the beam at the sample spot. Detection is also provided to detect and measure various toxins in, e.g., manufactured products including toys and electronics.
