Journal ArticleDOI
K α fluorescence measurement of relativistic electron transport in the context of fast ignition
Richard B. Stephens,R. A. Snavely,Yefim Aglitskiy,François Amiranoff,C. Andersen,Dimitri Batani,Sophie Baton,Thomas E. Cowan,R. R. Freeman,Todd H. Hall,S. P. Hatchett,J. M. Hill,M. H. Key,J A King,J. A. Koch,M. Koenig,A. J. Mackinnon,Kate Lancaster,E. Martinolli,Peter Norreys,E. Perelli-Cippo,M. Rabec Le Gloahec,C. Rousseaux,Joao Santos,F. Scianitti +24 more
TL;DR: A Monte Carlo model with a heuristic model for the electron injection gives a reasonable fit with data measured by imaging K(alpha) radiation from high- Z layers buried in low- Z foils.
Journal ArticleDOI
High-Resolution γ -Ray Radiography Produced by a Laser-Plasma Driven Electron Source
Y. Glinec,Jérôme Faure,L. Le Dain,S. Darbon,Takuya Hosokai,Joao Santos,Erik Lefebvre,Jean-Philippe Rousseau,Frédéric Burgy,Brigitte Mercier,Victor Malka +10 more
TL;DR: It is the first evidence of a gamma-ray source size of a few hundreds micrometers produced with laser-driven accelerators, consistent with results from Monte Carlo simulations.
Journal ArticleDOI
Fast electron transport in ultraintense laser pulse interaction with solid targets by rear-side self-radiation diagnostics.
Joao Santos,François Amiranoff,Sophie Baton,L. Gremillet,M. Koenig,E. Martinolli,M. Rabec Le Gloahec,Christophe Rousseaux,Dimitri Batani,A. Bernardinello,G. Greison,Todd H. Hall +11 more
TL;DR: Rear-side optical self-emission results from ultraintense laser pulse interactions with solid targets are reported, giving an indication of a temperature of a few hundred keV for the fast-electron population.
Journal ArticleDOI
Laser-driven platform for generation and characterization of strong quasi-static magnetic fields
Joao Santos,Mathieu Bailly-Grandvaux,L. Giuffrida,P. Forestier-Colleoni,Shinsuke Fujioka,Zhe Zhang,Ph. Korneev,Ph. Korneev,R. Bouillaud,S. Dorard,Dimitri Batani,M. Chevrot,J. E. Cross,R. Crowston,J. L. Dubois,J. Gazave,Gianluca Gregori,Emmanuel d'Humières,S. Hulin,K. Ishihara,Sadaoki Kojima,E. Loyez,J.-R. Marquès,Alessio Morace,Ph. Nicolaï,Olivier Peyrusse,Alexandre Poyé,D. Raffestin,J. Ribolzi,Markus Roth,Gabriel Schaumann,F. Serres,Vladimir Tikhonchuk,Ph Vacar,Nigel Woolsey +34 more
TL;DR: In this article, the reproducible generation of quasi-static magnetic fields at the kT-level with laser pulses was investigated. But the authors focused on the early stages of the target charging, up to ns, and then are disturbed by radiation and plasma effects.
Journal ArticleDOI
Observation of Laser-Pulse Shortening in Nonlinear Plasma Waves
Jérôme Faure,Y. Glinec,Joao Santos,F. Ewald,Jean-Philippe Rousseau,Sergey Kiselev,Alexander Pukhov,Tomonao Hosokai,Victor Malka +8 more
TL;DR: The temporal shortening of an ultraintense laser pulse interacting with an underdense plasma is measured, which shows the laser ponderomotive force excites a wakefield, which, along with relativistic self-phase modulation, broadens the laser spectrum and subsequently compresses the pulse.
