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…
Dephasingless laser wakefield acceleration in the bubble regime
Kyle G. Miller, Jacob R. Pierce, Manfred V. Ambat +5
Laser wakefield accelerators (LWFAs) have electric fields that are orders of magnitude larger than those of conventional accelerators, promising an attractive, small-scale alternat…
Spatiotemporal control of two-color terahertz generation
Tanner T. Simpson, Jeremy J. Pigeon, Manfred Virgil Ambat +5
A laser pulse composed of a fundamental and properly phased second harmonic exhibits an asymmetric electric field that can drive a time-dependent current of photoionized electrons.…
On the generation of ultra-bright and low energy spread electron beams in laser wakefield acceleration in a uniform plasma
Xinlu Xu, Thamine N. Dalichaouch, Jiaxin Liu +5
The quality of electron beams produced from plasma-based accelerators, i.e., normalized brightness and energy spread, has made transformative progress in the past several decades i…
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…
