Abstract
A system for x-ray analysis includes at least one x-ray source configured to emit x-rays. The at least one x-ray source includes at least one silicon carbide sub-source on or embedded in at least one thermally conductive substrate and configured to generate the x-rays in response to electron bombardment of the at least one silicon carbide sub-source. At least some of the x-rays emitted from the at least one x-ray source includes Si x-ray emission line x-rays. The system further includes at least one x-ray optical train configured to receive the Si x-ray emission line x-rays and to irradiate a sample with at least some of the Si x-ray emission line x-rays.
