Coincident electron-ion spectroscopy for fragmentation channel-resolved X-ray photoelectron spectroscopy

ORAL

Abstract

Coincident electron-ion spectroscopy used in conjunction with femtosecond soft X-ray pulses from a free-electron laser enables an atomistic view of ultrafast molecular dynamics. We discuss the design and implementation of a combined magnetic bottle electron spectrometer and ion time of flight spectrometer for soft X-ray measurements at the Linac Coherent Light Source. We demonstrate electron-ion covariance to study time-resolved molecular dynamics. This enables fragmentation channel-resolved X-ray photoelectron spectroscopy.
