High brightness multi-MeV photon source driven by a petawatt-scale laser wakefield accelerator
E. Gerstmayr, B. Kettle, M. J. V. Streeter +16
We present an experimental demonstration of a bright multi-MeV gamma source driven by a petawatt laser. The source generates on average photons above 1 MeV…
Roadmap for warm dense matter physics
Jan Vorberger, Frank Graziani, David Riley +71
This roadmap presents the state-of-the-art, current challenges and near future developments anticipated in the thriving field of warm dense matter physics. Originating from strongl…
Bounding elastic photon-photon scattering at MeV using a laser-plasma platform
R. Watt, B. Kettle, E. Gerstmayr +36
We report on a direct search for elastic photon-photon scattering using x-ray and photons from a laser-plasma based experiment. A gamma photon beam produced by a laser wakefiel…
Generation of photoionized plasmas in the laboratory of relevance to accretion-powered x-ray sources using keV line radiation
D. Riley, R. L. Singh, S White +12
We describe laboratory experiments to generate X-ray photoionized plasmas of relevance to accretion-powered X-ray sources such as neutron star binaries and quasars, with significan…
Extended X-ray absorption spectroscopy using an ultrashort pulse laboratory-scale laser-plasma accelerator
B. Kettle, C. Colgan, E. Los +21
Laser-driven compact particle accelerators can provide ultrashort pulses of broadband X-rays, well suited for undertaking X-ray absorption spectroscopy measurements on a femtosecon…
Monte Carlo modelling of the linear Breit-Wheeler process within the GEANT4 framework
R. A. Watt, S. J. Rose, B. Kettle +1
A linear Breit-Wheeler module for the code Geant4 has been developed. This allows signal-to-noise ratio calculations of linear Breit-Wheeler detection experiments to be performed w…
Narrow bandwidth, low-emittance positron beams from a laser-wakefield accelerator
M. J. V. Streeter, C. Colgan, N. Cavanagh +15
The rapid progress that plasma wakefield accelerators are experiencing is now posing the question as to whether they could be included in the design of the next generation of high-…
Transverse Oscillating Bubble Enhanced Laser-driven Betatron X-ray Radiation Generation
Rafal Rakowski, Ping Zhang, Kyle Jensen +10
Ultrafast high-brightness X-ray pulses have proven invaluable for a broad range of research. Such pulses are typically generated via synchrotron emission from relativistic electron…
The data-driven future of high energy density physics
Peter W. Hatfield, Jim A. Gaffney, Gemma J. Anderson +20
The study of plasma physics under conditions of extreme temperatures, densities and electromagnetic field strengths is significant for our understanding of astrophysics, nuclear fu…
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…
Fast electron propagation in Ti foils irradiated with sub-picosecond laser pulses at Wcm
M Makita, G Nersisyan, K McKeever +10
We have studied the propagation of fast electrons through laser irradiated Ti foils by monitoring the emission of hard X-rays and K-α radiation from bare foils and foils backed by…
