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…
Single-shot multi-keV X-ray absorption spectroscopy using an ultrashort laser wakefield accelerator source
B. Kettle, E. Gerstmayr, M. J. V. Streeter +19
Single-shot absorption measurements have been performed using the multi-keV X-rays generated by a laser wakefield accelerator. A 200 TW laser was used to drive a laser wakefield ac…
Collisionless shock acceleration of narrow energy spread ion beams from mixed species plasmas using 1 m lasers
A. Pak, S. Kerr, N. Lemos +15
Collisionless shock acceleration of protons and C ions has been achieved by the interaction of a 10 W/cm, 1 m laser with a near-critical density plasma. Ablati…
Sub-femtosecond electron bunches created by direct laser acceleration in a laser wakefield accelerator with ionization injection
N. Lemos, J. L. Shaw, K. A. Marsh +1
In this work, we will show through three-dimensional particle-in-cell simulations that direct laser acceleration in laser a wakefield accelerator can generate sub-femtosecond elect…
Satisfying the Direct Laser Acceleration Resonance Condition in a Laser Wakefield Accelerator
J. L. Shaw, N. Vafaei-Najafabadi, K. A. Marsh +4
In this proceeding, we show that when the drive laser pulse overlaps the trapped electrons in a laser wakefield accelerator (LWFA), those electrons can gain energy from direct lase…
