X-ray spectrometer and methods for use

Abstract

A spectrometer includes a crystal analyzer having a radius of curvature that defines a Rowland circle, a sample stage configured to support a sample such that the sample is offset from the Rowland circle, an x-ray source configured to emit unfocused x-rays toward the sample stage, and a position-sensitive detector that is tangent to the Rowland circle. A method performed via a spectrometer includes emitting, via an x-ray source, unfocused x-rays toward a sample that is mounted on a sample stage such that the sample is offset from the Rowland Circle, thereby causing the sample to emit x-rays that impinge on the crystal analyzer or transmit a portion of the unfocused x-rays to impinge on the crystal analyzer; scattering, via the crystal analyzer, the x-rays that impinge on the crystal analyzer; and detecting the scattered x-rays via a position-sensitive detector that is tangent to the Rowland circle.
