Effect of lattice excitations on transient near edge X-ray absorption spectroscopy
N. Rothenbach, M. E. Gruner, K. Ollefs +17
Time-dependent and constituent-specific spectral changes in soft near edge X-ray spectroscopy (XAS) of an [Fe/MgO] metal/insulator heterostructure upon laser excitation are ana…
SLAC UED LLRF System Upgrade
L. Ma, X. Shen, K. Kim +11
The SLAC mega-electron-volt (MeV) ultrafast electron diffraction (UED) instrument is a powerful "electron camera" for the study of time-resolved, ultrafast atomic & molecular dynam…
Femtosecond compression dynamics and timing jitter suppression in a terahertz-driven electron bunch compressor
E. C. Snively, M. A. K. Othman, M. Kozina +8
We present the first demonstration of THz-driven bunch compression and timing stabilization of a few-fC relativistic electron beam with kinetic energy of 2.5 MeV using quasi-single…
Nanopatterned electron beams for temporal coherence and deterministic phase control of x-ray free-electron lasers
W. S. Graves, S. L. Y. Chang, D. Dwyer +11
We demonstrate the ability to create electron beams with high-contrast, nanometer-scale density modulations as a first step toward developing full control of the phase fronts of an…
Theoretical and experimental electron diffraction intensity maps for single crystal silicon from an ultrafast source
L. E. Malin, W. S. Graves, M. Holl +5
Electron diffraction through a thin patterned silicon membrane can be used to create complex spatial modulations in electron distributions by varying the intensity of different ref…
Light-Induced Charge Density Wave in LaTe
Anshul Kogar, Alfred Zong, Pavel E. Dolgirev +18
When electrons in a solid are excited with light, they can alter the free energy landscape and access phases of matter that are beyond reach in thermal equilibrium. This accessibil…
Microscopic non-equilibrium energy transfer dynamics in a photoexcited metal/insulator heterostructure
N. Rothenbach, M. E. Gruner, K. Ollefs +15
The element specificity of soft X-ray spectroscopy makes it an ideal tool for analyzing the microscopic origin of ultrafast dynamics induced by localized optical excitation in meta…
