Abstract

An x-ray emission spectrometer, developed at beamline 9.3.1 of the Advance Light Source (ALS), Lawrence Berkeley National Laboratory (LBNL), will allow performing measurements of x-ray emission from molecules and materials in gas, liquid and solid phases with energy, angle and polarization dependence. A two-dimensional position-sensitive detector system with data acquisition software is developed for the spectrometer that allows collecting a complete x-ray emission spectrum simultaneously. Mechanical supports for detector mounting and a holder for solid samples are designed and manufactured. Energy calibration, resolution, and performance of the detector system and the spectrometer are tested by studying a solid potassium chloride (KCl) sample with photon energies in the vicinity of Cl K edge. A detectable energy range of 55--60 eV with a resolution of 0.2 eV are obtained and reported. The detector system and data acquisition software are suitable for x-ray emission measurements.
