Design optimization of a confocal x-ray fluorescence imaging capability for XFM and SRX at NSLS-II

Abstract

We propose a novel confocal x-ray fluorescence (XRF) imaging capability at the X-ray Fluorescence Microprobe (XFM) and Submicron Resolution X-ray Spectroscopy (SRX) beamlines of the National Synchrotron Light Source II (NSLS-II). Comparing to the conventional XRF tomography, this method can image a local region of interest within tens of minutes instead of hours. We will also present the optimized design of the confocal optic and estimated imaging resolution and throughput, based on the real parameters of the beamline photon delivery systems and the proposed confocal setup.
