Ultrafast Imaging of Laser Driven Shock Waves using Betatron X-rays from a Laser Wakefield Accelerator
J. C. Wood, D. J. Chapman, K. Poder +21
Betatron radiation from laser wakefield accelerators is an ultrashort pulsed source of hard, synchrotron-like x-ray radiation. It emanates from a centimetre scale plasma accelerato…

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…
