The chemRIXS Instrument for the LCLS-II X-Ray Free Electron Laser
David J. Hoffman, Douglas Garratt, Matthew Bain +28
The chemRIXS instrument at the Linac Coherent Light Source offers new opportunities for studying solution-phase systems with time-resolved soft X-ray spectroscopy through the recen…
Tracking Electron, Proton, and Solvent Motion in Proton-Coupled Electron Transfer with Ultrafast X-rays
Abdullah Kahraman, Michael Sachs, Soumen Ghosh +24
Proton-coupled electron transfer (PCET) is foundational to catalysis, bioenergetics, and energy conversion, yet capturing and disentangling the coupled motions of electrons, proton…
Imaging valence electron rearrangement in a chemical reaction using hard X-ray scattering
Ian Gabalski, Alice Green, Philipp Lenzen +24
We have observed the signatures of valence electron rearrangement in photoexcited ammonia using ultrafast hard X-ray scattering. Time-resolved X-ray scattering is a powerful tool f…
Spectrotemporal shaping of attosecond x-ray pulses with a fresh-slice free-electron laser
River R. Robles, Kirk A. Larsen, David Cesar +14
We propose a scheme allowing coherent shaping, i.e., controlling both the amplitude and phase, of attosecond x-ray pulses at free-electron lasers. We show that by seeding an FEL wi…
