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…

Bounding elastic photon-photon scattering at MeV using a laser-plasma platform
R. Watt, B. Kettle, E. Gerstmayr +36
We report on a direct search for elastic photon-photon scattering using x-ray and photons from a laser-plasma based experiment. A gamma photon beam produced by a laser wakefie…
