Multi-kilohertz laser plasma acceleration driven by an industrial-grade Yb:YAG laser
Bonaventura Farace, Nikita Khodakovskiy, Rob Shalloo +10
Laser plasma accelerators (LPAs) are a promising platform for compact radiation sources. For a wide range of applications, including radiotherapy, ultrafast electron diffraction an…
A laser-plasma platform for photon-photon physics
B. Kettle, D. Hollatz, E. Gerstmayr +35
We describe a laser-plasma platform for photon-photon collision experiments to measure fundamental quantum electrodynamic processes such as the linear Breit-Wheeler process with re…
Evolution of longitudinal plasma-density profiles in discharge capillaries for plasma wakefield accelerators
J. M. Garland, G. Tauscher, S. Bohlen +7
Precise characterization and tailoring of the spatial and temporal evolution of plasma density within plasma sources is critical for realizing high-quality accelerated beams in pla…
Plasma Lenses for Relativistic Laser Beams in Laser Wakefield Accelerators
Ming Zeng, Alberto Martinez de la Ossa, Kristjan Poder +1
Focusing petawatt-level laser beams to a variety of spot sizes for different applications is expensive in cost, labor and space. In this paper, we propose a plasma lens to flexibly…
A tunable plasma-based energy dechirper
R. D'Arcy, S. Wesch, A. Aschikhin +23
A tunable plasma-based energy dechirper has been developed at FLASHForward to remove the correlated energy spread of a 681~MeV electron bunch. Through the interaction of the bunch…
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…
Laser-driven plasma acceleration in a regime of strong-mismatch between the incident laser envelope and the nonlinear plasma response
A. A. Sahai, K. Poder, J. C. Wood +4
We explore a regime of laser-driven plasma acceleration of electrons where the radial envelope of the laser-pulse incident at the plasma entrance is strongly mismatched to the nonl…
Optimisation of the pointing stability of laser-wakefield accelerated electron beams
R. J. Garland, K. Poder, J. Cole +13
Laser-wakefield acceleration is a promising technique for the next generation of ultra-compact, high-energy particle accelerators. However, for a meaningful use of laser-driven par…
Direct observation of the injection dynamics of a laser wakefield accelerator using few-femtosecond shadowgraphy
A. Sävert, S. P. D. Mangles, M. Schnell +13
We present few-femtosecond shadowgraphic snapshots taken during the non-linear evolution of the plasma wave in a laser wakefield accelerator with transverse synchronized few-cycle…
Generation of a neutral, high-density electron-positron plasma in the laboratory
G. Sarri, K. Poder, J. Cole +17
We report on the laser-driven generation of purely neutral, relativistic electron-positron pair plasmas. The overall charge neutrality, high average Lorentz factor ($γ_{e/p} \appro…
