The Darkfield Approach to Measuring Vacuum Birefringence and Light-by-Light Couplings -- A Proof-of-Principle Experiment
Michal Smíd, Pooyan Khademi, Carsten Bähtz +29
Vacuum fluctuations give rise to effective nonlinear interactions between electromagnetic fields. These generically modify the characteristics of light traversing a strong-field re…
Shake-off in XFEL heated solid density plasma
G. O. Williams, L. Ansia, M. Makita +25
In atoms undergoing ionisation, an abrupt re-arrangement of free and bound electrons can lead to the ejection of another bound electron (shake-off). The spectroscopic signatures of…
Formation of high-aspect-ratio nanocavity in LiF crystal using a femtosecond of x-ray FEL pulse
Sergey S. Makarov, Sergey A. Grigoryev, Vasily V. Zhakhovsky +30
Sub-picosecond optical laser processing of metals is actively utilized for modification of a heated surface layer. But for deeper modification of different materials a laser in the…
Plasma screening in mid-charged ions observed by K-shell line emission
M. Šmıd, O. Humphries, C. Baehtz +24
Dense plasma environment affects the electronic structure of ions via variations of the microscopic electrical fields, also known as plasma screening. This effect can be either est…
Development towards high-resolution kHz-speed rotation-free volumetric imaging
Eleni Myrto Asimakopoulou, Valerio Bellucci, Sarlota Birnsteinova +19
X-ray multi-projection imaging (XMPI) provides rotation-free 3D movies of optically opaque samples. The absence of rotation enables superior imaging speed and preserves fragile sam…
Dielectronic satellite emission from a solid-density Mg plasma: relationship to models of ionisation potential depression
G. Pérez-Callejo, T. Gawne, T. R. Preston +15
We report on experiments where solid-density Mg plasmas are created by heating with the focused output of the Linac Coherent Light Source x-ray free-electron-laser. We study the K-…
Damage threshold in pre-heated materials exposed to intense X-rays
Nikita Medvedev, Zuzana Kuglerová, Mikako Makita +2
Materials exposed to ultrashort intense x-ray irradiation may experience various damaging conditions depending on the in-situ temperature. A pre-heated target exposed to intense x-…
Complex interferometry of magnetized plasma: accuracy and limitations
Iu. Kochetkov, T. Pisarczyk, M. Kalal +7
Expanding laser plasmas, produced by high energy laser radiation, possess both high thermal and magnetic field energy density. Characterization of such plasma is challenging but ne…
Time-resolved XUV Opacity Measurements of Warm-Dense Aluminium
S. M. Vinko, V. Vozda, J. Andreasson +20
The free-free opacity in plasmas is fundamental to our understanding of energy transport in stellar interiors and for inertial confinement fusion research. However, theoretical pre…
Identifiable Acetylene Features Predicted for Young Earth-like Exoplanets with Reducing Atmospheres undergoing Heavy Bombardment
P. B. Rimmer, M. Ferus, I. P. Waldmann +14
The chemical environments of young planets are assumed to be largely influenced by impacts of bodies lingering on unstable trajectories after the dissolution of the protoplanetary…
Contrasting behavior of covalent and molecular carbon allotropes exposed to extreme ultraviolet and soft x-ray free-electron laser radiation
M. Toufarová, V. Hájková, J. Chalupský +17
All carbon materials, e.g., amorphous carbon (a-C) coatings and C60 fullerene thin films, play an important role in short-wavelength free-electron laser (FEL) research motivated by…
Solid-to-solid phase transition from amorphous carbon to graphite nanocrystal induced by intense femtosecond x-ray pulses
J. Gaudin, J. Chalupský, M. Toufarová +22
We present the results of an experiment where amorphous carbon was irradiated by femtosecond x-ray free electron laser pulses. The 830 eV laser pulses induce a phase transition in…
