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…

Limitations of emittance and source size measurement of laser-accelerated electron beams using the pepper-pot mask method
F. C. Salgado, A. Kozan, D. Seipt +8
The pepper-pot method is a widely used technique, originally proposed for measuring the emittance of space-charge-dominated electron beams from radio-frequency photoinjectors. With…

A novel approach to electron data background treatment in an online wide-angle spectrometer for laser-accelerated ion and electron bunches
F. H. Lindner, J. H. Bin, F. Englbrecht +12
Laser-based ion acceleration is driven by electrical fields emerging when target electrons absorb laser energy and consecutively leave the target material. A direct correlation bet…
