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…
A Rate Model of Electron Populations for Non-linear High-Fluence X-ray Absorption Near-Edge Spectra
Robin Y. Engel, Markus Scholz, Jan O. Schunck +1
Absorbing a focused, femtosecond X-ray pulse from a Free-Electron Laser (FEL) can lead to extreme electronic excitations in solids. This excitation drives changes of the electronic…
Electron Dynamics at High-Energy Densities in Nickel from Non-linear Resonant X-ray Absorption Spectra
Robin Y. Engel, Oliver Alexander, Kaan Atak +40
The pulse intensity from X-ray free-electron lasers (FELs) can create extreme excitation densities in solids, entering the regime of non-linear X-ray-matter interactions. We show L…
Photon shot-noise limited transient absorption soft X-ray spectroscopy at the European XFEL
Loïc Le Guyader, Andrea Eschenlohr, Martin Beye +61
Femtosecond transient soft X-ray Absorption Spectroscopy (XAS) is a very promising technique that can be employed at X-ray Free Electron Lasers (FELs) to investigate out-of-equilib…
Effect of intense x-ray free-electron laser transient gratings on the magnetic domain structure of Tm:YIG
Victor Ukleev, Max Burian, Sebastian Gliga +13
Magnetic patterns can be controlled globally using fields or spin polarized currents. In contrast, the local control of the magnetization on the nanometer length scale remains chal…
Hard X-ray helical dichroism of disordered molecular media
Jeremy R. Rouxel, Benedikt Rosner, Dmitry Karpov +11
Chirality is a structural property of molecules lacking mirror symmetry that has strong implications in diverse fields, ranging from life to materials sciences. Established spectro…
