Electron-yield extended x-ray absorption fine structure with the use of a gas-flow electron detector

Abstract
We report the first electron-yield extended x-ray absorption fine-structure (EXAFS) measurements on a thick sample at ambient pressure using an ion chamber situated directly in the incident photon beam. An electron-detected EXAFS spectrum of an iron plate was acquired using a windowless, He-flow ion chamber at atmospheric pressure, thus extending the useful application of EXAFS to samples previously inaccessible by conventional techniques or not suited to ultrahigh vacuum environments.
