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…
Dual-energy electron beams from a compact laser-driven accelerator
J. Wenz, K. Khrennikov, A. Döpp +10
Ultrafast pump-probe experiments open the possibility to track fundamental material behaviour like changes in its electronic configuration in real time. To date, most of these expe…
Femtosecond profiling of shaped X-ray pulses
M. C. Hoffmann, I. Grguraš, C. Behrens +20
Arbitrary manipulation of the temporal and spectral properties of X-ray pulses at free-electron lasers (FELs) would revolutionize many experimental applications. At the Linac Coher…
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…
Laser-driven bunch compression for ultrashort free-electron laser pulses
Ph. Amstutz, W. Helml, S. Khan +4
Generation of ultrashort X-ray pulses in a free-electron laser relies on high-density electron bunches with a precisely adjusted current and energy distribution. To this end, robus…
