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…
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…
Experimental observation of a current-driven instability in a neutral electron-positron beam
J. Warwick, T. Dzelzainis, M. E. Dieckmann +16
We report on the first experimental observation of a current-driven instability developing in a quasi-neutral matter-antimatter beam. Strong magnetic fields ( 1 T) are measur…
Beamed neutron emission driven by laser accelerated light ions
S. Kar, A. Green, H. Ahmed +18
We report on the experimental observation of beam-like neutron emission with peak flux of the order of 10^9 n/sr, from light nuclei reactions in a pitcher-catcher scenario, by empl…
