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…
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…
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…
Temporal Feedback Control of High-Intensity Laser Pulses to Optimize Ultrafast Heating of Atomic Clusters
M. J. V. Streeter, S. J. D. Dann, J. D. E. Scott +27
We describe how active feedback routines can be applied at limited repetition rate (5 Hz) to optimize high-power TW) laser interactions with clustered gases. Optimization of…
Bright X-ray radiation from plasma bubbles in an evolving laser wakefield accelerator
M. S. Bloom, M. J. V. Streeter, S. Kneip +17
We show that the properties of the electron beam and bright x-rays produced by a laser wakefield accelerator can be predicted if the distance over which the laser self-focuses and…
