Photo-induced pair production and strong field QED on Gemini
CH Keitel, A Di Piazza, GG Paulus +12
The extreme intensities obtainable with lasers such as Gemini allow non-linear QED phenomena to be investigated according to our calculations. Electron-positron pair production fro…
Non-invasive characterisation of a laser-driven positron beam
Aaron Alejo, Guillermo Marrero Samarin, Richard Warwick +6
We report on an indirect and non-invasive method to simultaneously characterise the energy-dependent emittance and source size of ultra-relativistic positron beams generated during…
Laser-driven high-quality positron sources as possible injectors for plasma-based accelerators
Aaron Alejo, Roman Walczak, Gianluca Sarri
The intrinsic constraints in the amplitude of the accelerating fields sustainable by radio-frequency accelerators demand for the pursuit of alternative and more compact acceleratio…
One-dimensional thermal pressure-driven expansion of a pair cloud into an electron-proton plasma
M. E. Dieckmann, A. Alejo, G. Sarri +2
Recently a filamentation instability was observed when a laser-generated pair cloud interacted with an ambient plasma. The magnetic field it drove was strong enough to magnetize an…
Expansion of a radially symmetric blast shell into a uniformly magnetized plasma
M E Dieckmann, Q Moreno, D Doria +7
The expansion of a thermal pressure-driven radial blast shell into a dilute ambient plasma is examined with two-dimensional PIC simulations. The purpose is to determine if laminar…
General features of experiments on the dynamics of laser-driven electron-positron beams
J. R. Warwick, A. Alejo, T. Dzelzainis +14
The experimental study of the dynamics of neutral electron-positron beams is an emerging area of research, enabled by the recent results on the generation of this exotic state of m…
