Site-specific Interrogation of an Ionic Chiral Fragment During Photolysis Using an X-ray Free-Electron Laser

Markus Ilchen, Philipp Schmidt, Nikolay M. Novikovskiy +24

Short-wavelength free-electron lasers with their ultrashort pulses at high intensities have originated new approaches for tracking molecular dynamics from the vista of specific sit…

A self-referenced in-situ arrival time monitor for X-ray free-electron lasers

Michael Diez, Andreas Galler, Sebastian Schulz +11

We present a novel, highly versatile, and self-referenced arrival time monitor for measuring the femtosecond time delay between a hard X-ray pulse from a free-electron laser and an…

Clocking Auger Electrons

D. C. Haynes, M. Wurzer, A. Schletter +34

Intense X-ray free-electron lasers (XFELs) can rapidly excite matter, leaving it in inherently unstable states that decay on femtosecond timescales. As the relaxation occurs primar…
