Narrow bandwidth, low-emittance positron beams from a laser-wakefield accelerator
M. J. V. Streeter, C. Colgan, N. Cavanagh +15
The rapid progress that plasma wakefield accelerators are experiencing is now posing the question as to whether they could be included in the design of the next generation of high-…
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…
Extended X-ray absorption spectroscopy using an ultrashort pulse laboratory-scale laser-plasma accelerator
B. Kettle, C. Colgan, E. Los +21
Laser-driven compact particle accelerators can provide ultrashort pulses of broadband X-rays, well suited for undertaking X-ray absorption spectroscopy measurements on a femtosecon…
A laser-plasma platform for photon-photon physics
B. Kettle, D. Hollatz, E. Gerstmayr +35
We describe a laser-plasma platform for photon-photon collision experiments to measure fundamental quantum electrodynamic processes such as the linear Breit-Wheeler process with re…
