High brightness multi-MeV photon source driven by a petawatt-scale laser wakefield accelerator
E. Gerstmayr, B. Kettle, M. J. V. Streeter +16
We present an experimental demonstration of a bright multi-MeV gamma source driven by a petawatt laser. The source generates on average photons above 1 MeV…
Mechanisms to control laser-plasma coupling in laser wakefield electron acceleration
L. T. Dickson, C. I. D. Underwood, F. Filippi +16
Experimental results, supported by precise modelling, demonstrate optimisation of a plasma-based injector with intermediate laser pulse energy ( J), corresponding to a normalis…
Narrow bandwidth, low-emittance positron beams from a laser-wakefield accelerator
M. J. V. Streeter, C. Colgan, N. Cavanagh +15
The rapid progress that plasma wakefield accelerators are experiencing is now posing the question as to whether they could be included in the design of the next generation of high-…
Characterisation of Laser Wakefield Acceleration Efficiency with Octave Spanning Near-IR Spectrum Measurements
M. J. V. Streeter, Y. Ma, B. Kettle +25
We report on experimental measurements of energy transfer efficiencies in a GeV-class laser wakefield accelerator. Both the transfer of energy from the laser to the plasma wakefiel…
Automation and control of laser wakefield accelerators using Bayesian optimisation
R. J. Shalloo, S. J. D. Dann, J. -N. Gruse +26
Laser wakefield accelerators promise to revolutionise many areas of accelerator science. However, one of the greatest challenges to their widespread adoption is the difficulty in c…
A New Injection and Acceleration Scheme of Positrons in the Laser-Plasma Bubble Regime
Z. Y. Xu, C. F. Xiao, H. Y. Lu +15
A novel approach for positron injection and acceleration in laser driven plasma wakefield is proposed. A theoretical model is developed and confirmed through PIC simulation. One ri…
