Exact solution of the Gaunt-modified Landau-Lifshitz equation in a plane wave
S. A. Shekhanov, C. P. Ridgers
We analyze electron dynamics in a plane electromagnetic wave using the Landau-Lifshitz equation with a quantum radiation reaction correction modeled by a Gaunt factor. In this geom…
Bayesian Optimisation of Non-linear Breit-Wheeler Pair Production in Simulated Laser Experiments
Christopher Arran, Stuart Morris, Christopher P. Ridgers
High laser intensities enable the production of electron-positron pairs from bright gamma rays passing through strong fields. Potentially the most promising approach for all-optica…
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…
High-Energy Photon Generation from Self-Organized Plasma Cavities in Field-Enhanced Laser-Preplasma Interactions
Prokopis Hadjisolomou, Rashid Shaisultanon, Tae Moon Jeong +2
The interaction of an ultraintense Nd:glass laser pulse with a near-critical plasma self-organizes into a highly efficient -ray source. Three-dimensional particle-in-cell simul…
The effect of the electron's spin magnetic moment on quantum radiation in strong electromagnetic fields
Louis A. Ingle, Christopher D. Arran, Matthew Oxley +4
Ultra-intense laser pulses can create sufficiently strong fields to probe quantum electrodynamics effects in a novel regime. By colliding a 60 GeV electron bunch with a laser pulse…
Reaching extreme fields in laser-electron beam collisions with XUV laser light
Brandon K. Russell, Christopher P. Ridgers, Stepan S. Bulanov +8
Plasma-based particle accelerators promise to extend the revolutionary work performed with conventional particle accelerators to studies with smaller footprints, lower costs, and h…
