Dephasingless laser wakefield acceleration in a plasma waveguide
J. P. Palastro, K. G. Miller, C. D. Arrowsmith +10
Laser wakefield accelerators (LWFAs) provide extremely large accelerating gradients for compact electron accelerators and photon sources but are limited by dephasing, where trapped…
Accurate simulation of direct laser acceleration in a laser wakefield accelerator
Kyle G. Miller, John P. Palastro, Jessica L. Shaw +4
In a laser wakefield accelerator (LWFA), an intense laser pulse excites a plasma wave that traps and accelerates electrons to relativistic energies. When the pulse overlaps the acc…
Maximizing MeV x-ray dose in relativistic laser-solid interactions
Kyle G. Miller, Dean R. Rusby, Andreas J. Kemp +2
Bremsstrahlung x-rays generated in laser-solid interactions can be used as light sources for high-energy-density science. We present electron and x-ray spectra from particle-in-cel…
Extended particle absorber for efficient modeling of intense laser-solid interactions
Kyle G. Miller, Joshua May, Frederico Fiuza +1
An extended thermal particle boundary condition is devised to more efficiently and accurately model laser-plasma interactions in overdense plasmas. Particle-in-cell simulations of…
Predominant Contribution of Direct Laser Acceleration to High-Energy Electron Spectra in a Low-Density Self-Modulated Laser Wakefield Accelerator
P. M. King, K. Miller, N. Lemos +12
The two-temperature relativistic electron spectrum from a low-density (~cm) self-modulated laser wakefield accelerator (SM-LWFA) is observed to transition be…
