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…
Letter of Intent: Towards a Vacuum Birefringence Experiment at the Helmholtz International Beamline for Extreme Fields
N. Ahmadiniaz, C. Bähtz, A. Benediktovitch +49
Quantum field theory predicts a nonlinear response of the vacuum to strong electromagnetic fields of macroscopic extent. This fundamental tenet has remained experimentally challeng…
All-optical source size and emittance measurements of laser-accelerated electron beams
F. C. Salgado, A. Kozan, D. Seipt +8
Novel schemes for generating ultra-low emittance electron beams have been developed in past years and promise compact particle sources with excellent beam quality suitable for futu…
Experimental estimates of the photon background in a potential light-by-light scattering study
Leonard Doyle, Pooyan Khademi, Peter Hilz +4
High power short pulse lasers provide a promising route to study the strong field effects of the quantum vacuum, for example by direct photon-photon scattering in the all-optical r…
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…
Buffered spectrally-peaked proton beams in the relativistic-transparency regime
N. P. Dover, M. J. V. Streeter, C. A. J. Palmer +23
Spectrally-peaked proton beams ( MeV, MeV) have been observed from the interaction of an intense laser ( Wcm) with ultrathin CH foi…
Ultrasmall divergence of laser-driven ion beams from nanometer thick foils
J. H. Bin, W. J. Ma, K. Allinger +11
We report on experimental studies of divergence of proton beams from nanometer thick diamond-like carbon (DLC) foils irradiated by an intense laser with high contrast. Proton beams…
On Retardation Effects in Space Charge Calculations Of High Current Electron Beams
S. Becker, F. Grüner, D. Habs
Laser-plasma accelerators are expected to deliver electron bunches with high space charge fields. Several recent publications have addressed the impact of space charge effects on s…
