Ultra-short, MeV-scale laser-plasma positron source for positron annihilation lifetime spectroscopy
Thomas L. Audet, Aaron Alejo, Luke Calvin +10
Sub-micron defects represent a well-known fundamental problem in manufacturing since they can significantly affect performance and lifetime of virtually any high-value component. P…
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…
Production of photoionized plasmas in the laboratory using X-ray line radiation
S White, R Irwin, R Warwick +10
In this paper we report the experimental implementation of a theoretically-proposed technique for creating a photoionized plasma in the laboratory using X-ray line radiation. Using…
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 signatures of the quantum nature of radiation reaction in the field of an ultra-intense laser
K. Poder, M. Tamburini, G. Sarri +21
The description of the dynamics of an electron in an external electromagnetic field of arbitrary intensity is one of the most fundamental outstanding problems in electrodynamics. R…
Experimental evidence of radiation reaction in the collision of a high-intensity laser pulse with a laser-wakefield accelerated electron beam
J. M. Cole, K. T. Behm, T. G. Blackburn +21
The dynamics of energetic particles in strong electromagnetic fields can be heavily influenced by the energy loss arising from the emission of radiation during acceleration, known…
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…
