Electron Injection and Beam Dynamics in a Laser Wakefield Acceleration Driven by Laser Pulses Carrying Orbital Angular Momentum
Q. Qian, M. Li, Y. Ma +21
Laser pulses carrying orbital angular momentum (OAM) provide a new degree of freedom for controlling plasma-based accelerators. Here, we demonstrate experimentally laser wakefield…
Pair-loaded electron-only magnetic reconnection using laser-driven capacitor coils
Brandon K. Russell, Qian Qian, Rebecca Fitzgarrald +12
We propose and simulate a laboratory platform to study the effects of positrons in magnetic reconnection using laser-driven capacitor coils. Using particle-in-cell simulations, we…
Photon Phase-Space Dynamics in a Plasma Wakefield Accelerator
Neil Beri, John Palastro, Qian Qian +3
Frequency up-shifting of laser light in a beam-driven plasma wakefield has the potential to provide high-intensity sources of short wavelength radiation. Simulations have demonstra…
Bright polarised x-ray flashes from dense plasmas
Q. Qian, C. P. Ridgers, S. V. Bulanov +5
Creating a plasma dominated by strong-field QED (SFQED) effects is a major goal of new multi-PW laser facilities. This is motivated by the fact that the fundamental dynamics of suc…
Reaching extreme fields in laser-electron beam collisions with XUV laser light
Brandon K. Russell, Christopher P. Ridgers, Stepan S. Bulanov +8
Plasma-based particle accelerators promise to extend the revolutionary work performed with conventional particle accelerators to studies with smaller footprints, lower costs, and h…
