Megahertz-rate Ultrafast X-ray Scattering and Holographic Imaging at the European XFEL
Nanna Zhou Hagström, Michael Schneider, Nico Kerber +97
The advent of X-ray free-electron lasers (XFELs) has revolutionized fundamental science, from atomic to condensed matter physics, from chemistry to biology, giving researchers acce…
First functionality tests of a 64 x 64 pixel DSSC sensor module connected to the complete ladder readout
Mattia Donato, Karsten Hansen, Pradeep Kalavakuru +5
The European X-ray Free Electron Laser (XFEL.EU) will provide every 0.1 s a train of 2700 spatially coherent ultrashort X-ray pulses at 4.5 MHz repetition rate. The Small Quantum S…
Safety-Interlock System of the DSSC X-Ray Imager
Sneha Nidhi, Helmut Klaer, Karsten Hansen +3
In this paper, the DSSC safety-interlock system is introduced. It is designed to keep the DSSC mega-pixel camera in a safe-state. The system is composed of four inter-communicating…
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…
The interplay of local electron correlations and ultrafast spin dynamics in fcc Ni
Tobias Lojewski, Mohamed F. Elhanoty, Loïc Le Guyader +48
The complex electronic structure of metallic ferromagnets is determined by a balance between exchange interaction, electron hopping leading to band formation, and local Coulomb rep…
Analysis of long-lived effects in high-repetition-rate stroboscopic transient X-ray absorption experiments on thin films
Tobias Lojewski, Loïc Le Guyader, Naman Agarwal +41
Time-resolved X-ray absorption spectroscopy (tr-XAS) has been shown to be a versatile measurement technique for investigating non-equilibrium dynamics. Novel X-ray free electron la…
Multiscale Modeling and Simulation of Organic Solar Cells
Carlo de Falco, Matteo Porro, Riccardo Sacco +1
In this article, we continue our mathematical study of organic solar cells (OSCs) and propose a two-scale (micro- and macro-scale) model of heterojunction OSCs with interface geome…
Hierarchical Electrochemical Modeling and Simulation of Bio-Hybrid Interfaces
Emanuela Abbate, Matteo Porro, Thierry Nieus +1
In this article we propose and investigate a hierarchy of mathematical models based on partial differential equations (PDE) and ordinary differential equations (ODE) for the simula…
Solution Map Analysis of a Multiscale Drift-Diffusion Model for Organic Solar Cells
Maurizio Verri, Matteo Porro, Riccardo Sacco +1
In this article we address the theoretical study of a multiscale drift-diffusion (DD) model for the description of photoconversion mechanisms in organic solar cells. The multiscale…
