"Beam `a la carte": laser heater shaping for attosecond pulses in a multiplexed x-ray free-electron laser
Siqi Li, Zhen Zhang, Shawn Alverson +19
Electron beam shaping allows the control of the temporal properties of x-ray free-electron laser pulses from femtosecond to attosecond timescales. Here we demonstrate the use of a…
Attosecond Delays in X-ray Molecular Ionization
Taran Driver, Miles Mountney, Jun Wang +34
The photoelectric effect is not truly instantaneous, but exhibits attosecond delays that can reveal complex molecular dynamics. Sub-femtosecond duration light pulses provide the re…
Experimental Demonstration of Attosecond Pump-Probe Spectroscopy with an X-ray Free-Electron Laser
Zhaoheng Guo, Taran Driver, Sandra Beauvarlet +47
Pump-probe experiments with sub-femtosecond resolution are the key to understanding electronic dynamics in quantum systems. Here we demonstrate the generation and control of sub-fe…
A compact single-shot soft X-ray photon spectrometer for free electron laser diagnostics
Kirk A. Larsen, Kurtis Borne, Razib Obaid +13
The photon spectrum from free-electron laser (FEL) light sources offers valuable information in time-resolved experiments and machine optimization in the spectral and temporal doma…
