Journal ArticleDOI
Intense High-Energy Proton Beams from Petawatt-Laser Irradiation of Solids
R. Snavely,R. Snavely,M. H. Key,S. P. Hatchett,Thomas E. Cowan,Markus Roth,T. W. Phillips,M. A. Stoyer,E. A. Henry,T. C. Sangster,M. S. Singh,Scott Wilks,A. J. Mackinnon,A. A. Offenberger,Deanna Marie Pennington,K. Yasuike,A. B. Langdon,Barbara F. Lasinski,J. Johnson,Michael D. Perry,E. M. Campbell +20 more
TL;DR: An intense collimated beam of high-energy protons is emitted normal to the rear surface of thin solid targets irradiated at 1 PW power and peak intensity 3x10(20) W cm(-2).
Journal ArticleDOI
Energetic proton generation in ultra-intense laser–solid interactions
Scott Wilks,A. B. Langdon,Thomas E. Cowan,Markus Roth,M. S. Singh,Stephen P. Hatchett,M. H. Key,Deanna Marie Pennington,A. J. Mackinnon,R. Snavely +9 more
TL;DR: In this paper, an attempt is made to explain the physical process present that will explain the presence of these energetic protons, as well as explain the number, energy, and angular spread of the protons observed in experiment.
Journal ArticleDOI
Enhancement of Proton Acceleration by Hot-Electron Recirculation in Thin Foils Irradiated by Ultraintense Laser Pulses
A. J. Mackinnon,Yasuhiko Sentoku,P. K. Patel,D. W. Price,S. P. Hatchett,M. H. Key,C. Andersen,R. Snavely,R. R. Freeman +8 more
TL;DR: Observations are consistent with modeling showing an enhanced density of MeV electrons at the rear surface for the thinnest targets, which predicts an increased acceleration and higher proton energies.
Journal ArticleDOI
Proton radiography as an electromagnetic field and density perturbation diagnostic (invited)
A. J. Mackinnon,P. K. Patel,Richard Town,M. J. Edwards,T. W. Phillips,S. C. Lerner,D. W. Price,Damien Hicks,M. H. Key,S. P. Hatchett,Scott Wilks,Marco Borghesi,Lorenzo Romagnani,Satyabrata Kar,Toma Toncian,Georg Pretzler,O. Willi,M. Koenig,E. Martinolli,S. Lepape,Alessandra Benuzzi-Mounaix,Patrick Audebert,J. C. Gauthier,J A King,R. Snavely,R. R. Freeman,T. Boehlly +26 more
TL;DR: In this paper, grid deflectometry techniques have been applied to proton radiography to obtain precise measurements of proton beam angles caused by electromagnetic fields in laser produced plasmas.
Journal ArticleDOI
Ion acceleration from the shock front induced by hole boring in ultraintense laser-plasma interactions.
H. Habara,Kate Lancaster,S. Karsch,C. D. Murphy,Peter Norreys,Roger Evans,Marco Borghesi,Lorenzo Romagnani,Matthew Zepf,Takayoshi Norimatsu,Yusuke Toyama,Ryosuke Kodama,J A King,R. Snavely,Kramer Akli,B. Zhang,R. R. Freeman,S. P. Hatchett,A. J. Mackinnon,P. K. Patel,M. H. Key,Christian Stoeckl,Richard B. Stephens,Ricardo Fonseca,L. O. Silva +24 more
TL;DR: Two-dimensional particle-in-cell simulations indicate that the acceleration of the ions is caused by a collisionless shock formation, which has implications for modeling energy transport in solid density plasmas as well as cone-focused fast ignition using the next generation PW lasers currently under construction.
