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…
Ion-motion-driven enhancement of energy coupling and stability in relativistic laser-microchannel interaction
K. Weichman, M. VanDusen-Gross, G. Bruhaug +5
For sufficiently short relativistic-intensity laser pulses, the disparity in time scales for electron and ion motion causes ions to behave as a fixed, neutralizing background. As t…
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…
Testing strong-field QED with the avalanche precursor
A. A. Mironov, S. S. Bulanov, A. Di Piazza +8
A two-beam high-power laser facility is essential for the study of one of the most captivating phenomena predicted by strong-field quantum electrodynamics (QED) and yet unobserved…
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…
Joule-Class Pulsed THz Sources from Microchannel Targets
G. Bruhaug, H. G. Rinderknecht, K. Weichman +9
Inference of joule-class THz radiation sources from microchannel targets driven with hundreds of joule, picosecond lasers is reported. THz sources of this magnitude are useful for…
