Journal ArticleDOI
Monoenergetic beams of relativistic electrons from intense laser–plasma interactions
Stuart Mangles,C. D. Murphy,C. D. Murphy,Zulfikar Najmudin,Alexander Thomas,John Collier,A. E. Dangor,E. J. Divall,Peta Foster,J. G. Gallacher,C. J. Hooker,Dino A. Jaroszynski,A. J. Langley,Warren Mori,Peter Norreys,Frank Tsung,R. Viskup,B. Walton,Karl Krushelnick +18 more
TL;DR: High-resolution energy measurements of the electron beams produced from intense laser–plasma interactions are reported, showing that—under particular plasma conditions—it is possible to generate beams of relativistic electrons with low divergence and a small energy spread.
Journal ArticleDOI
A compact synchrotron radiation source driven by a laser-plasma wakefield accelerator
Hans-Peter Schlenvoigt,K. Haupt,Alexander Debus,F. Budde,O. Jäckel,Sebastian M. Pfotenhauer,Heinrich Schwoerer,Heinrich Schwoerer,Erich G. Rohwer,J. G. Gallacher,Enrico Brunetti,Richard Shanks,Sally Wiggins,Dino A. Jaroszynski +13 more
TL;DR: In this paper, the first successful combination of a laser-plasma wakefield accelerator with an undulator to generate visible synchrotron radiation was demonstrated, and the authors showed the potential for ultracompact and versatile laser-based radiation sources from the infrared to X-ray energies.
Journal ArticleDOI

TL;DR: This work will discuss how a laser-driven plasma wakefield accelerator can be used to produce radiation with unique characteristics over a very large spectral range.
Journal ArticleDOI
Evidence of photon acceleration by laser wake fields
C. D. Murphy,C. D. Murphy,R. M. G. M. Trines,Jorge Vieira,Albert Reitsma,Robert Bingham,John Collier,E. J. Divall,Peta Foster,C. J. Hooker,A. J.

TL;DR: In this paper, the detection of a large-amplitude laser-driven wake field is reported for the first time, demonstrating photon acceleration, and several features characteristic of photon acceleration in wake fields, such as splitting of the main spectral peak and asymmetries between the blueshift and redshift for large shifts are observed.

TL;DR: The duration of laser-accelerated, quasimonoenergetic electron bunches is demonstrated to be shorter than the drive laser pulse, but similar to the plasma period.
