摘要： An x-ray source assembly includes an anode having a spot upon which electrons impinge based on power level supplied to the assembly, and an optic coupled to receive divergent x-rays generated at the spot and transmit output x-rays from the assembly. A control system is provided for maintaining intensity of the output x-rays dynamically during operation of the x-ray source assembly, notwithstanding a change in at least one operating condition of the x-ray source assembly, by changing the power level supplied to the assembly. The control system may include at least one actuator for effecting the change in the power level supplied to the assembly, by, e.g., controlling a power supply associated with the assembly. The control system may also change the temperature and/or the position of the anode to maintain the output intensity.

摘要： A measurement and processing technique enabling x-ray analysis systems to handle dynamically changing samples and other conditions resulting in both significant and insignificant measurement changes. A stream of input values related to measured compositional information of the sample is received, and a stream of output compositional values is produced. The current output value y[n] is set as a function of the received input value x[n] if the received input value x[n] differs from x[n−1] by more than an intensity-dependent deviation limit; and alternatively the current output y[n] is set as a function of the previous output y[n−1] and the received input value x[n] if the received input value x[n] differs from x[n−1] by less than the intensity-dependent deviation limit. The intensity-dependent deviation limit is maintained as a function of the intensity of the measured compositional information. Types of dynamically changing samples to which the technique is applicable include fluid streams and sheet production, monitored by, e.g., XRF and XRD systems.

摘要： A method and apparatus for analyzing fluids by means of x-ray fluorescence. The method and apparatus are applicable to any fluid, including liquids and gases, having at least one component that emits x-ray fluorescence when exposed to x-rays. The apparatus includes an x-ray source (82) including an x-ray tube (64) having improved heat dissipating properties due to the thermal coupling of the x-ray tube with a thermally-conductive, dielectric material (70, 1150). The x-ray tube also includes means for aligning (100, 2150, 2715) the x-ray tube with the x-ray source housing whereby the orientation of the x-ray beam produced by the x-ray source can be optimized, and stabilized various over operating conditions. The method and apparatus may also include an x-ray detector having a small-area, for example, a PIN-diode type semiconductor x-ray detector (120), that can provide effective x-ray detection at room temperature. One aspect of the disclosed invention is most amenable to the analysis of sulfur in petroleum-based fuels.

摘要： Method for the identification of a homogeneous material (e.g. a liquid) in a container (e.g. a bottle) by measuring its X-ray or gamma spectrum and deriving its specific attenuation function. The method comprises building a database of the attenuation functions of empty containers, of containers filled with various fluid materials and of the contained fluid materials itself (by subtracting or devoluting the empty-container-attenuation-function from the filled-container-attenuation-function), recording the spectrum of an unknown material in a container and comparing this spectrum to the spectra in the database.
