Journal ArticleDOI
Laser acceleration of quasi-monoenergetic MeV ion beams
Bjorn Hegelich,Brian J. Albright,J. A. Cobble,Kirk Flippo,Samuel A. Letzring,M. Paffett,H. Ruhl,H. Ruhl,Jörg Schreiber,Roland Schulze,Juan C. Fernández +10 more
TL;DR: Quasi-monoenergetic laser-driven C5+ ions with a vastly reduced energy spread are reported, which may enable significant advances in the development of compact MeV ion accelerators, new diagnostics, medical physics, inertial confinement fusion and fast ignition.
Journal ArticleDOI
Isochoric heating of solid-density matter with an ultrafast proton beam.
P. K. Patel,A. J. Mackinnon,M. H. Key,Thomas E. Cowan,Mark Foord,M Allen,Dwight Price,H. Ruhl,P. T. Springer,Richard B. Stephens +9 more
TL;DR: The technique described of ultrafast proton heating provides a unique method for creating isochorically heated high-energy density plasma states.
Journal ArticleDOI
Ultralow Emittance, Multi-MeV Proton Beams from a Laser Virtual-Cathode Plasma Accelerator
Thomas E. Cowan,Thomas E. Cowan,Julien Fuchs,Julien Fuchs,Julien Fuchs,H. Ruhl,H. Ruhl,Andreas Kemp,Andreas Kemp,Patrick Audebert,Markus Roth,Richard B. Stephens,I. Barton,Abel Blazevic,E. Brambrink,J. Cobble,Juan C. Fernández,J. C. Gauthier,M. Geissel,Manuel Hegelich,J. L. Kaae,Stefan Karsch,G. P. Le Sage,Samuel A. Letzring,M. Manclossi,S. Meyroneinc,A. Newkirk,Henri Pépin,N. Renard-LeGalloudec +28 more
TL;DR: The laminarity of high-current multi-MeV proton beams produced by irradiating thin metallic foils with ultraintense lasers has been measured and appears to be at least 100-fold better than conventional accelerator beams.
Journal ArticleDOI
Macroscopic evidence of soliton formation in multiterawatt laser-plasma interaction
Marco Borghesi,Sergei V. Bulanov,D. H. Campbell,R. J. Clarke,T. Zh. Esirkepov,Marco Galimberti,Leonida A. Gizzi,A. J. Mackinnon,N. M. Naumova,Francesco Pegoraro,H. Ruhl,Angelo Schiavi,Oswald Willi +12 more
TL;DR: In this paper, a macroscopic bubble-like structure has been detected through the deflection that the associated electric charge separation causes in a proton probe beam, interpreted as the remnants of a cloud of relativistic solitons generated in the plasma by the ultraintense laser pulse.
Journal ArticleDOI
Proton imaging: a diagnostic for inertial confinement fusion/fast ignitor studies
Marco Borghesi,Angelo Schiavi,D. H. Campbell,M. G. Haines,Oswald Willi,A. J. Mackinnon,Leonida A. Gizzi,Marco Galimberti,R. J. Clarke,H. Ruhl +9 more
TL;DR: In this paper, the authors present measurements of transient electric fields in laser-plasmas and around laser-irradiated targets under various interaction conditions, including ultraintense interactions with solid targets.
