The inadequacy of a magnetohydrodynamic approach to the Biermann Battery
C. P. Ridgers, C. Arran, J. J. Bissell +1
Magnetic fields can be generated in plasmas by the Biermann battery when the electric field produced by the electron pressure gradient has a curl. The commonly employed magnetohydr…

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…

Overcoming the dephasing limit in multiple-pulse laser wakefield acceleration
James D. Sadler, Christopher Arran, Hui Li +1
The electric field in laser-driven plasma wakefield acceleration is orders of magnitude higher than conventional radio-frequency cavities, but the energy gain is limited by dephasi…
