Heteroatom Position Controls Ultrafast Photodynamics of Oxazole and Isoxazole
Briony Downes-Ward, Paul Javed, Huynh V. S. Lam +27
The ultrafast photochemistry of heterocyclic compounds is central to photobiology and materials chemistry, yet direct experimental observation of their structural dynamics remains…
Ray-tracing image simulations of transparent objects with complex shape and inhomogeneous refractive index
Armin Kalita, Bryan Oller, Thomas Paula +18
Optical images of transparent three-dimensional objects can be different from a replica of the object's cross section in the image plane due to refraction at the surface or in the…
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…
Attosecond Coherent Electron Motion in a Photoionized Aromatic Molecule
Taran Driver, Zhaoheng Guo, Erik Isele +50
In molecular systems, the ultrafast motion of electrons initiates the process of chemical change. Tracking this electronic motion across molecules requires coupling attosecond time…
Ultrafast symmetry control in photoexcited quantum dots
Burak Guzelturk, Joshua Portner, Justin Ondry +23
Symmetry control is essential for realizing unconventional properties, such as ferroelectricity, nonlinear optical responses, and complex topological order, thus it holds promise f…
Design and Performance of a Magnetic Bottle Electron Spectrometer for High-Energy Photoelectron Spectroscopy
Kurtis Borne, Jordan T ONeal, Jun Wang +19
We describe the design and performance of a magnetic bottle electron spectrometer~(MBES) for high-energy electron spectroscopy. Our design features a ~m long electron drif…
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…
Femtosecond electronic and hydrogen structural dynamics in ammonia imaged with ultrafast electron diffraction
Elio G. Champenois, Nanna H. List, Matthew Ware +18
Directly imaging structural dynamics involving hydrogen atoms by ultrafast diffraction methods is complicated by their low scattering cross-sections. Here we demonstrate that megae…
The Time-resolved Atomic, Molecular and Optical Science Instrument at the Linac Coherent Light Source
Peter Walter, Timur Osipov, Ming-Fu Lin +39
The newly constructed Time-resolved atomic, Molecular and Optical science instrument (TMO), is configured to take full advantage of both linear accelerators at SLAC National Accele…
