Abstract:
1. An x-ray system for exciting a sample under x-ray analysis, comprising: a curved, point-to-point focusing monochromating optic for redirecting and focusing a monochromatic x-ray beam from an x-ray source towards a first focal point; a second, convergent-beam-to-point focusing optic positioned within, and receiving, the monochromatic x-ray beam, and directing a focused x-ray beam towards a second focal point on the sample; and a detector positioned near the sample to collect radiation from the sample as a result of the focused x-ray beam; wherein the curved monochromating optic produces a beam spot size at the first focal point larger than a beam spot size produced by the second optic at the second focal point, wherein a beam spot size on the sample is thereby reduced using the second optic; wherein the second optic is positioned within the monochromatic x-ray beam, before the first focal point, thereby receiving the monochromatic x-ray beam as it converges toward the first focal point.
