Electron Dynamics in a Wakefield Accelerator 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 experimentally demonstrate OAM-driven laser…
Report of Snowmass 21 Accelerator Frontier Topical Group 6 on Advanced Accelerators
C. Geddes, M. Hogan, P. Musumeci +1
The Snowmass 2021 Accelerator Frontier topical group \# 6 on Advanced Accelerator Concepts, covers new R\&D concepts for particle acceleration, generation, and focusing. Based on c…
Whitepaper submitted to Snowmass21: Advanced accelerator linear collider demonstration facility at intermediate energy
C. Benedetti, S. S. Bulanov, E. Esarey +30
It is widely accepted that the next lepton collider beyond a Higgs factory would require center-of-mass energy of the order of up to 15 TeV. Since, given reasonable space and cost…
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…
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…
General features of experiments on the dynamics of laser-driven electron-positron beams
J. R. Warwick, A. Alejo, T. Dzelzainis +14
The experimental study of the dynamics of neutral electron-positron beams is an emerging area of research, enabled by the recent results on the generation of this exotic state of m…
