High brightness multi-MeV photon source driven by a petawatt-scale laser wakefield accelerator
E. Gerstmayr, B. Kettle, M. J. V. Streeter +16
We present an experimental demonstration of a bright multi-MeV gamma source driven by a petawatt laser. The source generates on average photons above 1 MeV…

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…
