Ultrafast loss of lattice coherence in the light-induced structural phase transition of VO

A. S. Johnson, D. Moreno-Mencía, E. B. Amuah +5

In solids, the response of the lattice to photo-excitation is often described by the inertial evolution on an impulsively modified potential energy surface which leads to coherent…

Correlation Driven Transient Hole Dynamics Resolved in Space and Time in the Isopropanol Molecule

T. Barillot, O. Alexander, B. Cooper +46

The possibility of suddenly ionized molecules undergoing extremely fast electron hole dynamics prior to significant structural change was first recognized more than 20 years ago an…

Machine learning applied to single-shot x-ray diagnostics in an XFEL

A. Sanchez-Gonzalez, P. Micaelli, C. Olivier +39

X-ray free-electron lasers (XFELs) are the only sources currently able to produce bright few-fs pulses with tunable photon energies from 100 eV to more than 10 keV. Due to the stoc…

Mitigation Plans for the Microbunching-Instability-Related COTR at ASTA/FNAL

A. H. Lumpkin, M. Church, A. S. Johnson

At the Advanced Superconducting Test Accelerator (ASTA) now under construction at Fermilab, we anticipate the appearance of the microbunching instability related to the longitudina…

Upgrades of beam diagnostics in support of emittance-exchange experiments at the Fermilab A0 photoinjector

A. H. Lumpkin, A. S. Johnson, J. Ruan +4

The possibility of using electron beam phase space manipulations to support a free-electron laser accelerator design optimization has motivated our research. An on-going program de…
