We report on a direct search for elastic photon-photon scattering using x-ray and $\gamma$ photons from a laser-plasma based experiment. A gamma photon beam produced by a laser wakefield accelerator provided a broadband gamma spectrum extending to ab

R., Treffert, F., Xu, N., Palmer, C. A. J.

The interaction of relativistically intense lasers with opaque targets represents a highly non-linear, multi-dimensional parameter space. This limits the utility of sequential 1D scanning of experimental parameters for the optimisation of secondary r

X-ray absorption spectroscopy using an ultrafast laboratory-scale laser-plasma accelerator source

Autor: Kettle, B., Colgan, C., Los, E., Gerstmayr, E., Streeter, M. J. V., Albert, F., Astbury, S., Baggott, R. A., Cavanagh, N., Falk, K., Hyde, T. I., Lundh, O., Rajeev, P. P., Riley, D., Rose, S.

The absorption profile of the copper K-edge was measured over a 250 eV window using ultrashort X-rays from a laser-plasma wakefield accelerator. For the first time with a femtosecond probe, Extended X-ray Absorption Fine Structure (EXAFS) features we
