Characterization and automated optimization of laser-driven proton beams from converging liquid sheet jet targets

G. D. Glenn, F. Treffert, H. Ahmed +31

Compact, stable, and versatile laser-driven ion sources hold great promise for applications ranging from medicine to materials science and fundamental physics. While single-shot so…

Automated control and optimisation of laser driven ion acceleration

B. Loughran, M. J. V. Streeter, H. Ahmed +32

The interaction of relativistically intense lasers with opaque targets represents a highly non-linear, multi-dimensional parameter space. This limits the utility of sequential 1D s…

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…

Ultrafast opacity in borosilicate glass induced by picosecond bursts of laser-driven ions

B. Dromey, L. Stella, D. Adams +22

Direct investigation of ion-induced dynamics in matter on picosecond (ps, 10-12 s) timescales has been precluded to date by the relatively long nanosecond (ns, 10-9 s) scale ion pu…

Fast electron propagation in Ti foils irradiated with sub-picosecond laser pulses at Wcm

M Makita, G Nersisyan, K McKeever +10

We have studied the propagation of fast electrons through laser irradiated Ti foils by monitoring the emission of hard X-rays and K-α radiation from bare foils and foils backed by…
