X-RAY SOURCE ASSEMBLY HAVING ENHANCED OUTPUT STABILITY, AND FLUID STREAM ANALYSIS APPLICATIONS THEREOF |
摘要 |
A technique for analyzing fluids by means of x-ray fluorescence applicable to any fluid, including liquids and gases, which emit 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 a thermally-conductive, dielectric material ( 70, 1150 ). The x-ray tube also includes means for aligning ( 100, 2150, 2715 ) the tube with the source housing whereby the orientation of the x-ray beam produced by the source can be optimized, and stabilized over various 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. |
