Microcoulomb-level electron beam and multi-Joule hard X-rays driven by a high-efficiency laser-plasma accelerator
B. Mahieu, L. Ribotte, W. Cayzac +38
We report on the production of ultrahigh-charge relativistic electron beams and the development of a laser-wakefield acceleration platform at the LMJ facility. Making use of the ki…
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…
Characterisation of Laser Wakefield Acceleration Efficiency with Octave Spanning Near-IR Spectrum Measurements
M. J. V. Streeter, Y. Ma, B. Kettle +25
We report on experimental measurements of energy transfer efficiencies in a GeV-class laser wakefield accelerator. Both the transfer of energy from the laser to the plasma wakefiel…
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…
Laser-Plasma Interactions Enabled by Emerging Technologies
J. P. Palastro, F. Albert, B. Albright +51
An overview from the past and an outlook for the future of fundamental laser-plasma interactions research enabled by emerging laser systems.
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…
Ultrafast Imaging of Laser Driven Shock Waves using Betatron X-rays from a Laser Wakefield Accelerator
J. C. Wood, D. J. Chapman, K. Poder +21
Betatron radiation from laser wakefield accelerators is an ultrashort pulsed source of hard, synchrotron-like x-ray radiation. It emanates from a centimetre scale plasma accelerato…
Self-modulated laser wakefield accelerators as x-ray sources
N. Lemos, J. L. Martins, F. S. Tsung +5
The development of a directional, small-divergence, and short-duration picosecond x-ray probe beam with an energy greater than 50 keV is desirable for high energy density science e…
