摘要： An apparatus and method for providing focused x-ray, gamma-ray, charged particle and neutral particle, including neutron, radiation beams (18) with a controllable amount of divergence are diclosed. The apparatus features a novel use of a radiation blocking structure (54, 142, 218, 240) which, when combined with multiple-channel total reflection optics (10), increases the versality of the optics by providing user-controlled output-beam divergence.

摘要： X-ray fluorescence (XRF) spectroscopy systems and methods are provided. One system (100) includes a source (110) of x-ray radiation and an excitation optic (120) disposed between the x-ray radiation source (110) and the sample (130) for collecting x-ray radiation from the source and focusing the x-ray radiation to a focal point on the sample to incite at least one analyte in the sample to fluoresce. The system (100) further includes an x-ray fluorescence detector (150) and a collection optic (140) comprising a doubly curved diffracting optic disposed between the sample and the x-ray fluorescence detector for collecting x-ray fluorescence from the focal point on the sample and focusing the fluorescent x-rays towards the x-ray fluorescence detector.

摘要： A system comprising a novel combination of a multiple-channel monolithic capillary optic (44) and an x-ray source (30) with a spot size (42) of less than 300 microns to produce a high intensity small diameter x-ray beam is described. A system of this invention can be easily adapted for use in the analysis of small samples where an intense quasi-parallel, or converging x-ray beam is required.
