Multistage Coupling of Laser-Wakefield Accelerators with Curved Plasma Channel
J. Luo, M. Chen, W. Y. Wu +8
Multistage coupling of laser-wakefield accelerators is essential to overcome laser energy depletion for high-energy applications such as TeV level electron-positron colliders. Curr…
Strong coupling constant extraction from high-multiplicity Z+jets observables
Mark Johnson, Daniel Maître
We present a strong coupling constant extraction at Next-to-Leading Order QCD accuracy using ATLAS Z+2,3,4 jets data. This is the first extraction using processes with a dependency…
Energy efficiency studies for dual-grating dielectric laser-driven accelerators
Yelong Wei, Mark Ibison, Javier Resta-Lopez +7
Dielectric laser-driven accelerators (DLAs) can provide high accelerating gradients in the GV/m range due to their having higher breakdown thresholds than metals, which opens the w…
Simulation studies for dielectric wakefield programme at CLARA facility
Thomas H Pacey, Yuri Saveliev, Guoxing Xia +1
Short, high charge electron bunches can drive high magnitude electric fields in dielectric lined structures. The interaction of the electron bunch with this field has several appli…
Electron spin polarization in realistic trajectories around the magnetic node of two counter-propagating, circularly polarized, ultra-intense lasers
Dario Del Sorbo, Daniel Seipt, Alexander G. R. Thomas +1
It has recently been suggested that two counter-propagating, circularly polarized, ultra-intense lasers can induce a strong electron spin polarization at the magnetic node of the e…
The deconstructed hydrodynamic model for plasmonics
Paul Kinsler
I give an exact but deconstructed version of the second-order wave-like equation that encapsulates the hydrodynamic model for plasmonics. Comprising two first order equations, the…
Experimental studies of 7-cell dual axis asymmetric cavity for energy recovery linac
I. V. Konoplev, K. Metodiev, A. J. Lancaster +3
High average current, transportable energy recovery linacs (ERLs) can be very attractive tools for a number of applications including next generation high-luminosity, compact light…
Simulations of an energy dechirper based on dielectric lined waveguides
Y. Nie, G. Xia, T. Pacey
Terahertz frequency wakefields can be excited by ultra-short relativistic electron bunches travelling through dielectric lined waveguide (DLW) structures. These wakefields can eith…
Observation of Laser Power Amplification in a Self-Injecting Laser Wakefield Accelerator
M. J. V. Streeter, S. Kneip, M. S. Bloom +17
We report on the depletion and power amplification of the driving laser pulse in a strongly-driven laser wakefield accelerator. Simultaneous measurement of the transmitted pulse en…
Back-reaction on background fields: a coherent state approach
Anton Ilderton, Daniel Seipt
There are many situations in which a strong electromagnetic field may be approximated as a fixed background. Going beyond this approximation, i.e. accounting for the back-reaction…
Enhanced ultrafast relaxation rate in the Weyl semimetal phase of measured by time-and angle-resolved photoelectron spectroscopy
A. Crepaldi, G. Autès, G. Gatti +18
has recently been shown to realize in its low-temperature phase the type-II Weyl semimetal (WSM). We investigated by time- and angle- resolved photoelectron spect…
An extended model of the quantum free-electron laser
M. S. Brown, J. R. Henderson, L. T. Campbell +1
Previous models of the quantum regime of operation of the Free Electron Laser (QFEL) have performed an averaging and the application of periodic boundary conditions to the coupled…
Interaction between electrostatic collisionless shocks generates strong magnetic fields
E. Boella, K. Schoeffler, N. Shukla +3
The head-on collision between electrostatic shocks is studied via multi-dimensional Particle-In-Cell simulations. It is found that the shock velocities drop significantly and a str…

Faraday's Law and Magnetic Induction: cause and effect, experiment and theory
Paul Kinsler
Faraday's Law of induction is often stated as "a change in magnetic flux causes an EMF"; or, more cautiously, "a change in magnetic flux is associated with an EMF"; It is as well t…
